Normal baby growth chart

The First 24 Months| Pampers

Children come in all shapes and sizes, and all babies grow at their own pace. At your child’s regular health checkups, your little one’s healthcare provider will plot certain measurements on a baby growth chart to make sure they’re on the right track. The chart might look daunting, but your provider can help you understand this useful tool and what the results mean for your child. To make it easier, we'll show you how to read a baby growth chart and interpret the results.

What Are Baby Growth Charts?

Baby growth charts are important tools healthcare providers use to check your little one’s overall health. The charts assess how your baby is growing compared with other children of the same age and gender, and to see how your child is developing over time. Growth standards used for babies under 24 months old are based on the following:

• Head circumference. This is the distance around the largest part of the head and indicates how your baby’s brain is growing.

• Weight-for-length. This measures your baby’s weight along with their length (height).

• Weight-for-age. This measurement tracks your baby’s weight at a particular age.

• Length-for-age. This measures your baby’s length (height) at a particular age.

Your child’s healthcare provider will use different growth charts for baby boys and girls, and different charts for babies younger than 24 months and for those 2 years and older.

It's helpful to know that these charts offer information that your provider can assess in the context of other baby developmental milestones and genetic factors. You can find and download the charts below.

When and How Is Your Baby Measured?

You probably chose your child’s healthcare provider while pregnant, and your baby’s initial office visit will be within a few days of their birth or shortly after you leave the hospital. Starting with this first appointment, checking your baby’s growth will become a routine part of each visit, whether your little one is 1 month or 1 year. Initially, your baby's checkups will take place every few weeks, and then every few months until your baby turns 1. Your provider will let you know if you need to visit more often and when to schedule future appointments. Don’t hesitate to ask any questions you might have about your baby’s health and development—your child’s healthcare provider is your partner and can reassure you that you’re doing a great job and help you resolve any issues that pop up! Here’s how babies are usually weighed and measured:

• Head circumference: The healthcare provider will wrap a soft tape measure around the widest part of your baby’s head, from above the eyebrows, passing above the ears, to the back of the head.

• Length: Measuring the length (a.k.a. height) of a wriggly baby may be tricky, but your provider is an expert at this! As your little one lies on a flat table, the provider will gently stretch out your baby’s legs to get an accurate measurement from the top of their head to the soles of their feet.

• Weight: With your baby undressed, your child’s provider will likely use a baby scale to get the most accurate reading.

How to Read a Baby Growth Chart

Once you have your measurements, you might look at a baby growth chart and wonder how you are supposed to make sense of it. Your baby’s healthcare provider can help you understand your child’s results and plot them on the chart at the health checkup, but in the meantime here’s a quick guide on how to read these charts. Remember, it’s important to use the baby boy growth charts if you have a boy and the baby girl growth charts if you have a girl.

Head Circumference Percentile

Although these charts look like something only Einstein could figure out, they’re actually fairly simple to read once you get the hang of it. To find your baby’s head circumference percentile in the growth chart linked above, following these steps:

1. Find your baby’s age in months at the top of the chart. Only some months are numbered, but each month is represented by a vertical line.

2. Find your baby’s head circumference measurement on the left side (measurements are provided in both inches and centimeters).

3. Follow these horizontal and vertical lines until they intersect. In most cases, they will intersect on a curved line.

4. Follow the curved line to the right until it ends, and here you’ll see a number on a white background. This number indicates your baby’s head circumference percentile on the growth chart.

Weight-for-Length Percentile

Now that you’ve found your baby’s head circumference percentile on the growth chart, it will be easier to do the same for their weight. Follow the steps below:

1. Find your child’s length in inches or centimeters at the bottom of the grid.

2. Find your child’s weight (in pounds or kilograms) on the left side of the grid.

3. Follow the horizontal and vertical lines of these two measurements until they intersect on the growth curve.

4. Follow the curved line until the end to find your baby’s weight-for-length percentile on the growth chart.

Length-for-Age Percentile

To determine your baby’s length-for-age (height) percentile on the growth chart, follow the steps below:

1. Find your baby’s length (in inches or centimeters) on the left side of the grid.

2. Find your child’s age in months at the bottom of the chart.

3. Track these horizontal and vertical lines until they intersect on the growth curve.

4. Follow that curve until the end, where the percentiles are written on a white, shaded background.

Weight-for-Age Percentile

Lastly, use the baby growth chart to track your little one’s percentile for weight using the following steps:

1. Find your baby’s weight (pounds or kilograms) on the right side of the grid.

2. Find your child’s age in months at the top of the chart.

3. Follow these horizontal and vertical lines until they intersect on the curved line.

4. Follow that curved line until the end, where the percentiles are written on a white, shaded background.

How to Interpret Baby Growth Chart Percentiles

Your child’s healthcare provider is the best person to explain these results to you. Remember, the charts show the typical growth patterns for baby boys and girls, and there is a wide range of healthy results. There’s no ideal result when viewed individually, but, ideally, your child would follow along the same growth pattern (the curved line) over time. As a result, their height and weight would grow in proportion to one another.

What Are the Percentiles?

But, this one point doesn't show the complete picture. Your child’s provider will assess several values over time to determine the trend of how your baby is growing compared to the average growth curve on the chart. Try not to become too focused on a single number. There is a wide range of healthy sizes and lengths, and many factors influence your child’s growth, including genetics, environmental factors, nutrition, activity levels, and health conditions. Another thing to consider is when babies have growth spurts, which can vary from child to child. For example, breastfed and formula-fed babies grow in slightly different patterns. Breastfed babies typically put on weight more slowly than formula-fed babies, and formula-fed infants typically go through a growth spurt and gain weight more quickly after 3 months of age.

With all these different factors at play, it’s important to assess these percentiles over time and with your child’s provider.

What Happens if My Baby’s Growth Pattern Changes?

A different growth pattern doesn’t always indicate a problem. Your child may simply be experiencing a growth spurt, which is partly why it’s so important to look at these percentiles over time. However, your child’s healthcare provider will also investigate a growth pattern change to rule out any issues. Typically, a healthy, well-nourished baby grows at a fairly predictable rate. Any change in this rate can help your baby’s provider detect and address any feeding, developmental, or medical issues.

What Happens if My Baby Is Above or Below the Average?

Most children fall between the 3rd and 97th percentiles on baby growth charts for head circumference, weight, and length (height). But if your child does not, know that there are many factors at play, and that your child’s provider will consider other developmental milestones and family genetics. Baby growth chart percentiles aren’t like an algebra exam. Just because your little one is in the 50th percentile doesn’t mean there’s a problem! In fact, that figure means your baby is right in the middle of the average. What’s more important is how your child grows over time. Plus, some families might have fast-growing babies, while others have slow and steady gainers. Regardless of what you see on your baby’s growth chart, try not to worry, and keep these individual differences in mind as you follow your child's development. If the healthcare provider determines that your baby is overweight, underweight, growing too fast, or growing too slowly, trust that your little one is in good care, and follow the provider’s recommendations.

The Bottom Line

Baby growth charts, whether for boys or girls, can be confusing at first glance. In the end, it’s always best to look at your baby’s growth chart percentiles together with their healthcare provider over time, and to avoid comparing your child to others. Instead, focus on all of the growing your little one is doing! And, if your baby’s healthcare provider says they’re on the right track, you can take pride in your little one’s progress regardless of the value on the chart. In fact, you’ll probably be delighted (and maybe even a little surprised) when you see how big your baby is now compared to the day they were born. Your little one is a moving, grooving, and growing machine, and there’s so much to look forward to, such as watching them start to crawl and walk, hearing those first laughs, and helping them develop those fine motor skills.

Average baby weight: Chart and development

Weight is one indicator of good nutrition and physical development. It can therefore be helpful to know about babies’ average weight month by month.

First, it is worth noting that average weight is not “normal” weight. Just like adults, babies come in all shapes and sizes. If a baby’s weight is in a lower percentile, this does not necessarily signal a problem with their growth or physical development. With this in mind, using a weight chart can help a person generally track their baby’s growth.

The Centers for Disease Control and Prevention (CDC) recommend using the World Health Organization (WHO) weight chart for babies up to 2 years of age.

This article describes the average weight of a baby month by month from birth. It also explores what can affect a baby’s weight.

According to the WHO, the average birth weight of a full-term male baby is 7 pounds (lb) 6 ounces (oz), or 3.3 kilograms (kg). The average birth weight of a full-term female is 7 lb 2 oz, or 3.2 kg.

The average weight of a baby born at 37–40 weeks ranges from 5 lb 8 oz to 8 lb 13 oz. This is 2.5 to 4 kg.

At delivery, experts consider a low birth weight to be less than 5 lb 8 oz, or 2.5 kg.

It is common for babies to lose around 10% of their weight shortly after birth. This decrease is mostly due to fluid loss and usually nothing to worry about. Most babies gain back this weight within 1 week.

Weight charts can help a person tell what percentile their baby’s weight falls into. For example, if their weight is in the 60th percentile, it means that 40% of babies of the same age and sex weigh more, and 60% of these babies weigh less.

This does not necessarily mean that any baby weighs too much or too little. It can simply indicate where a baby’s weight falls on a spectrum.

The chart below shows baby weights in the 50th percentile. This is the average weight. Male babies tend to weigh a little more than female babies, so the chart is divided by sex.

Baby age	Female 50th percentile weight	Male 50th percentile weight
Birth	7 lb 2 oz (3.2 kg)	7 lb 6 oz (3.3 kg)
1 month	9 lb 4 oz (4.2 kg)	9 lb 14 oz (4.5 kg)
2 months	11 lb 5 oz (5. 1 kg)	12 lb 4 oz (5.6 kg)
3 months	12 lb 14 oz (5.8 kg)	14 lb 1 oz (6.4 kg)
4 months	14 lb 3 oz (6.4 kg)	15 lb 7 oz (7.0 kg)
5 months	15 lb 3 oz (6.9 kg)	16 lb 9 oz (7.5 kg)
6 months	16 lb 1 oz (7.3 kg)	17 lb 8 oz (7.9 kg)
7 months	16 lb 14 oz (7.6 kg)	18 lb 5 oz (8.3 kg)
8 months	17 lb 8 oz (7.9 kg)	18 lb 15 oz (8.6 kg)
9 months	18 lb 2 oz (8.2 kg)	19 lb 10 oz (8.9 kg)
10 months	18 lb 11 oz (8.5 kg)	20 lb 3 oz (9.2 kg)
11 months	19 lb 4 oz (8.7 kg)	20 lb 12 oz (9.4 kg)
12 months	19 lb 12 oz (8.9 kg)	21 lb 4 oz (9.6 kg)

Babies grow and gain weight the fastest within the first 6 months of life. Although this can vary, babies tend to gain around 4–7 oz, or 113–200 grams (g), per week in the first 4–6 months.

Weight gain then slows slightly, with an average gain of around 3–5 oz (about 85–140 g) per week when the baby is 6–18 months. On average, babies triple their birth weight by their first birthday.

Growth patterns do not follow a clear schedule, however.

Some babies gain weight steadily and stay in the same percentile, or close to it, for several months. Others gain weight rapidly, signalling a growth spurt, which can happen at any time. This may move a baby into a new weight percentile.

It is important not to focus on weight as the only indicator of physical development. Other measurements of this development include the baby’s length and head circumference.

Considering all three measurements gives doctors an idea about how the baby is growing, compared with other babies of the same age and sex.

Meanwhile, it is also important to keep other developmental milestones in mind. Various checklists of milestones by age are available, including one from Pathways. org, which is endorsed by organizations such as the American Academy of Pediatrics and the National Association of Pediatric Nurse Practitioners.

For anyone looking for more information about what influences the weight of a baby, several factors can be involved, including:

Sex

Male newborns tend to be bigger than female newborns, and they typically gain weight a little faster during infancy.

Nutrition

Weight gain and growth rates can also depend on whether the baby consumes breast milk or formula.

The American Academy of Pediatrics notes that breastfed babies gain weight and grow faster than formula-fed babies during the first 6 months.

However, that rate can shift during the next 6 months. Breastfed babies may gain weight and grow more slowly than formula-fed babies when they are aged 6 months to 1 year.

Medical conditions

Underlying health issues can cause a baby to gain weight more slowly. For example, babies with congenital heart irregularities may gain weight at a slower rate than babies without this condition.

Health issues that affect nutrient absorption or digestion, such as celiac disease, may also lead to slow weight gain.

Prematurity

Babies born prematurely may grow and gain weight more slowly during their first year than babies born at full term.

However, many babies born prematurely gain weight rapidly and “catch up” by about their first birthday.

The average birth weight for full-term male babies is 7 lb 6 oz, or 3.3 kg. For female babies born full-term, the average birth weight is 7 lb 2 oz, or 3.2 kg.

Baby weight charts can help a healthcare team track a baby’s physical development by comparing the baby’s weight with the weights of others of the same age and sex.

Still, a doctor usually looks for steady growth, rather than a target percentile, when assessing a baby’s physical development. And even if a baby’s weight is in a lower percentile, they will not necessarily be a small adult — just as longer babies do not necessarily become tall adults.

Knowing about average weights by month can help people gauge their babies’ physical development, but doctors also look for other important indicators, such as length and head circumference.

Healthcare professionals also take into account whether a baby is generally hitting other milestones on time. And by taking a detailed medical history, they can rule out any medical conditions or nutritional considerations that may be preventing a baby from gaining weight appropriately.

Tables of weight and height of the child by months and by years. For boys and for girls.

The height and weight of a child are the main indicators of his physical development. That is why immediately after the birth of the baby, it is imperative to measure the weight of his body and the length of the body and continue to weigh himself daily at the same time until discharge from the hospital.

There are many factors that affect the physical development of a child, for example:0010

psychological situation in the family, at school, lack of sleep, etc.

How to understand what is the norm?

The All-Russian Health Organization recommended special tables for matching the height and weight of children, or as they are called, centile tables. At each examination, the pediatrician measures the height and weight of the child, compares the obtained values ​​\u200b\u200bwith the standard indicators. Such tables allow you to identify obvious pathologies, for a more accurate analysis, the doctor calculates additional indicators using special formulas.

Deviations of weight or height from tabular values ​​

There is no need to panic if there is a minimal discrepancy with the indicated values ​​in the table, and here's why:

1. First of all, the child's height and weight charts contain reference indicators , what should ideally be the weight and height of the child, without taking into account many other factors . Sometimes parents of premature babies mistakenly use a standard table for comparison, while there are special tables for assessing the development of children born prematurely.
2. The rate of growth and weight gain for each child is unique . In the first year of life, babies develop in leaps and bounds. For example, during the period of introducing complementary foods, the weight of the baby may not reach the “norm” due to adaptation to a new type of food, and not because of pathology.

This does not mean that deviations from the norm should be ignored , but it is better to regard them as an occasion to pay attention and consult a specialist in order to identify possible health problems, or to make sure that they are not present.

What can cause obvious deviations from the norm?

Earlier we talked about minor deviations from the norm and that there is no need to be scared if your child is not growing and gaining weight strictly according to the chart. But what to do if the values ​​of the essential have gone beyond the limits of the permissible parameters , or are they at the intersection of norm and pathology?

Reasons for possible deviations can be divided into two groups:

1. Non-endocrine:

• Constitutional growth retardation . Or in another way, the syndrome of late puberty. One of the variants of the norm, when the puberty jump occurs later than in other children.
• Family stunting . It has a hereditary predisposition, in the family of such children there are relatives with short stature. Growth retardation manifests itself from early childhood.
• Prematurity, intrauterine and postnatal injuries.
• Genetic syndromes . As a rule, they have many clinical manifestations, one of which is growth retardation.
• Chronic diseases of the cardiovascular, bronchopulmonary systems, gastrointestinal tract, as well as anemia.
• Fasting .
• Taking certain medications .

2. Endocrine:

• Growth hormone deficiency . Biologically active substance, which is the main regulator of the growth process after 2 years.
• Deficiency of thyroid hormones . More often of a congenital nature, it is clinically characterized by a delay in physical and intellectual development from birth.
• Type 1 diabetes mellitus . A disease in which, due to insulin deficiency, the flow of glucose into the cells of the body is impaired, the so-called. "starvation" of cells, as a result, growth rates slow down.
• Itsenko-Cushing's disease (or syndrome) . At the same time, the production of hormones of the adrenal cortex, glucocorticoids, is increased, which in large doses leads to a violation of the secretion of growth hormone.
• Rickets . A lack of vitamin D leads to bone destruction and skeletal deformities, which in turn is manifested, among other things, by a decrease in growth.
• Other rare disorders of the endocrine system.

As you can see, there are a lot of reasons.

If the child's growth is stunted, parents should consult a doctor to identify the causes of short stature and correct it in a timely manner.

Which specialist should I contact? First, you should make an appointment with a pediatrician. Also, in most cases, consultation with a pediatric endocrinologist is required.

Remember that for the normal growth of the child you need a complete, balanced diet with enough vitamins and minerals, as well as dosed physical activity.

Children's height and weight standards - WHO data

Children's height and weight standards - WHO data

A child's height and weight are parameters that parents are most concerned about. What are the norms of height and weight for children of different ages? We invite you to familiarize yourself with the data of the World Health Organization. Based on large-scale studies, scientists have established normal parameters for the development of children, which can be relied upon.

The height and weight of a child is the most exciting topic for parents

One of the most common questions that all mothers have is the rate of growth and weight of the child in the first months of the baby's life. Based on the recommended norms, you can understand whether your child is developing correctly and whether it is worth taking him to the doctor. A child's height and weight are important parameters by which parents can evaluate a child's health.

Often, parents are faced with rather conflicting information about what weight and height of a child is normal. Moreover, different doctors may interpret the current indicators in a child in different ways. We hasten to inform you that the World Health Organization has established height and weight standards for boys and girls. This is the most up-to-date data on which to rely when interpreting the parameters of height and weight of children.

Standards of weight and height of a child, which are widely used today, in fact, do not reflect the real state of affairs - how exactly a child should grow and develop in order for his health to be in the best possible condition. Such data simply shows how the average child grows.

With regard to the standards developed by WHO, these data are more than just reference parameters for height and weight. The WHO tables on the norms of height and weight of children enable parents to determine the optimal values ​​for the physical development of babies, taking into account the weight and height of children of different ages.

Child height and weight: how the norms were set

The 2002 UNICEF and WHO guidelines state that breastfeeding is the best form of feeding for babies. Mother's milk is the ideal food for the healthy growth and development of children. During the first six months, experts from WHO and UNICEF recommend feeding children exclusively with breast milk. After this period, children must receive adequate complementary foods for adequate growth and development. In this case, breastfeeding should continue up to two years or more (at the request of the mother).

One of the distinguishing features of modern norms for the development and growth of children is the understanding of breastfeeding as a certain biological norm. A healthy child, not overweight and breastfeeding, was taken as a reference. In this regard, the new norms for the growth and weight of babies differ from those that were adopted on the basis of an analysis of the parameters of all children (who were both breastfed and bottle-fed).

To establish new norms for the development of children's growth, experts examined about 9thousands of children raised in a supportive environment that includes breastfeeding, a healthy diet, and the prevention of infectious diseases and other negative manifestations. Moreover, the mothers of these children refrained from bad habits during pregnancy and breastfeeding. It was a large-scale project sponsored by the World Health Organization and a number of UN non-governmental organizations. As a result of the data obtained, graphs of weight and height were drawn up for boys and girls aged 0 to 10 years. It is noteworthy that these graphs show not only the absolute values ​​​​of height and weight, but also the relationship with each other, and this ratio is very important for understanding how harmoniously a child develops. WHO tables will help calculate the norm of weight and height of a child.

WHO Table No. 1: Height (in cm) and weight (in kg) of boys in the first year of life

By three months, boys grow to 61.4 cm and weigh 6.400 g. Low values ​​will be parameters below 59.4 cm 5.700 g, and high values ​​will be values ​​above 63.5 cm and 7.200 g.
