If you have a baby, you’re probably concerned about making sure they have enough water and nutrients to stay healthy. Even though your baby drinks breast milk or formula, is that enough to keep them hydrated? Yes. Here’s what you need to know.

How Infants Stay Hydrated

As an adult, water is the most hydrating thing you can drink. It quenches your thirst and helps all of your systems stay balanced. 

But children under a year old don’t need water like adults do. It can actually be dangerous for them. Babies get all their hydration from breast milk or formula.

When Babies Can Start Drinking Water

A baby should drink only breast milk or formula until they’re six months old. It has all the hydration and nutrition they need in the early months. 

Even when you start giving them purees or table food at around 6 months of age, breast milk and formula are still more important than water. But you can begin to introduce it. 

When babies are between 6 and 12 months of age, breast milk or formula continues to be a priority over water. But if you offer breast milk or formula first, you can then offer water, 2-3 ounces at a time. At this age, 4-8 ounces a day of water is enough. More than that may lead to water intoxication.

Making Sure Water Is Baby-Safe

Before using water to mix baby formula or offering a baby water for the first time, consider testing your tap water. While tap water may have fluoride that helps prevent tooth decay, it could also contain levels of lead that are unsafe for babies.

Most tap water in the U.S. is safe, with a few exceptions:

• If you have untested well water.
• If your water source has recently been contaminated.
• If your baby has low immunity‌.

If you’re worried about lead exposure and traces of chemicals in your water, install a filtration system or use distilled water instead which can be easily purchased.

Considerations for mixing formula with water. If you use tap water to mix formula, mix only one bottle at a time. Don’t  use tap water to mix formula in bulk amounts. 

A similar rule applies to water that you’ve boiled. Refrigerate boiled water within an hour, and throw it away if you don’t use it within 24 hours. Always allow the water to cool completely before mixing the formula. Hot water can burn your baby.

When you purchase formula, carefully follow the instructions on the container for mixing it with water. Instructions vary by brand. This will ensure your baby gets the right amount of nutrients and hydration. 

Mixing in too much formula may lead to constipation or dehydration. Mixing in too little formula may lead to malnutrition or water intoxication.

Risks of Water for Infants

Drinking too much water at a young age is very dangerous. Water causes an imbalance in sodium levels that may lead to:

• Seizures
• Brain damage
• Coma‌
• Death

Water intoxication leads to changes in behavior such as:

• Confusion
• Drowsiness
• Muscle cramps and twitching
• Nausea and vomiting
• Difficulty breathing‌
• Weakness

Watch for signs of water intoxication and call your doctor immediately if you have any concerns.

Water as Your Baby Grows

Between the ages of 1 and 3, your toddler needs 4 cups of liquid per day. This is a transitional period that should include both water and breastmilk or formula. The older your child gets, the more water they need. There are several ways you can encourage your older child to drink enough water.

Flavor water with fresh fruit. Water is healthier than juice since many children’s juices are full of sugar. If your child prefers the taste of juice, use fresh fruit to flavor their water. Lemon, berries, mint, and cucumber are great additions.

Offer more fruits and vegetables. Encourage your child to eat more fruits and vegetables with high water content. These help them stay hydrated without forcing them to drink more water than they want. Hydrating vegetables include cucumber, tomato, zucchini, celery, and iceberg lettuce. Hydrating fruits include strawberries, watermelon, blueberries, cantaloupe, and grapefruit.

Make creative ice cubes and popsicles. Puree your fruit of choice with water and freeze it into ice cubes or popsicle molds.

Provide special drinkware. Use a fancy cup with favorite colors or characters. When you find ways to make water fun, your child is more likely to enjoy drinking it.

when, how much and what kind of water to give a newborn and children with breastfeeding and artificial?

Does a newborn baby need water? This question worries many young mothers, while the recommendations of doctors differ: some believe that the baby does not need any additional fluid, while others argue that the child needs water. Let's try to figure out how and when to give your baby water and how water for newborns differs from ordinary drinking water.

Breast milk is both food and drink for the baby, since it is 90% water and in the first weeks of life it is able to maintain the fluid balance at the required level. Mother's milk helps the process of digestion, as it contains all the enzymes necessary for this. Moreover, the mother's body is able to very accurately adapt to the needs of the child, adjusting the composition of milk depending on the situation. For example, if a baby needs more fluid, he will breastfeed more often and, as a result, receive more unsaturated foremilk, which quenches thirst and restores electrolyte balance.

It may seem that the child does not need water, but this is not so: there are situations when it is indispensable. Indeed, up to three months, babies should be given water only on the recommendation of a doctor. Babies older than four months can be fed quite calmly - contrary to popular belief, this does not lead to the child's refusal to breastfeed, and even more so to his exhaustion. If the baby drinks water with pleasure, there are no contraindications for this. But the lack of fluid for the baby is very dangerous - adults should not forget that the metabolic rate in newborns is very high and moisture loss is also significant.

However, parents need to know when and how much water should be given to newborns and how the type of feeding affects fluid requirements.

Water while breastfeeding

Newborns can drink water from four to five months. It is better to do this between feedings - if the baby feels thirsty, he drinks water with pleasure. How much water can you give a newborn? Here, as in adults, everything is individual. Usually, pediatricians advise giving a certain amount of liquid per day with a calculation of no more than 100 ml per kg of weight, but this also includes breast milk. So the water, in fact, remains 30-70 ml.

You can feed your newborn from a bottle with a nipple or even from a spoon – this will facilitate the introduction of complementary foods later, because the baby will already know how to use a spoon. But the most important rule is voluntariness: if the child is naughty and does not want to drink, you should not insist.

Water with formula or formula feeding

Formula feeding differs markedly from natural feeding - infant formula contains much more protein than mother's milk, so the baby needs additional fluids. Lack of water, especially when feeding too rich formula, can lead to constipation in children. The extra water will help empty the bowels and make your baby feel better.

With artificial or mixed feeding, water can be given earlier than with breastfeeding. Unlike formulas, which should be 36-37°C, the water can be slightly cooler: 26-30°C in the first one or two months of life, and at an older age - about 20°C.

All paediatricians agree that with the introduction of complementary foods, water becomes essential. Usually, babies who received only milk or formula before the introduction of complementary foods begin to drink solid food only after one to two months. And babies, accustomed to water, are not capricious and drink it with pleasure after each feeding.

When is water given to newborns?

Babies should be given water some time after meals and between feedings. Do not forget that the volume of the child's stomach is very small, which means that he simply cannot drink a large amount of water at once - a few teaspoons will suffice for a start.

In some situations, the need for fluid increases. Most often, overheating and very dry indoor air leads to a lack of moisture. Many parents are so afraid of colds in a child that they wrap him in clothes and do not observe the temperature regime in the children's room, which leads to a decrease in air humidity and dehydration of the baby's body. The optimal temperature for a nursery is 20 ° C, and humidity is 50–70%. Dry air leads to increased breathing, a decrease in the protective functions of the body, difficulty swallowing and colic. And in summer, in hot weather, overheating is added to all these problems, because of which the child sweats and loses precious moisture. It is easy to determine the first signs of dehydration: this is rare urination (normally - about 20 times a day), dryness of the mucous membranes, skin, tongue. In such a situation, water is simply necessary.

Many paediatricians recommend giving newborns water to drink even when they are sick - with fever or colic, which are easily recognized by tucked up legs, a tense tummy and restlessness of the child. A few sips of warm water can also help with hiccups.

What kind of water should I give my baby?

Boiled water and water from open sources

Many parents believe that children should drink boiled water, but this is a misconception. Boiling leads to the destruction of only part of the bacteria, in addition, such water contains in excess chloride compounds that are very harmful to young children. Water from open sources is also dangerous - it may contain a high content of nitrates and bacteria from the soil and other harmful impurities. And, of course, babies should not be given healing mineral or sparkling water.

In addition, water from ordinary filter jugs designed to purify water for adults is not suitable for infants.

Bottled water

Baby water is sold in pharmacies and supermarkets. As a rule, on the bottle it has a special marking and information that this product has been tested by the Russian Academy of Medical Sciences. Water for a baby is different from the usual "adult" drinking water. In particular, other requirements for the content of minerals are imposed on it:

• total minerals less than 200–300 mg/l;
• calcium - less than 60 mg/l;
• potassium less than 5–20 mg/l;
• sodium less than 20 mg/l;
• magnesium - less than 10-35 mg/l.

Boiling such water is not required, but it can be stored only for a day from the moment of opening and always in the refrigerator. The best container for bottled baby water is a glass bottle or polycarbonate container (bottles made of this material are marked with the number seven on the bottom).

Specially filtered water

Regardless of the brand of bottled baby water and price, it is impossible to be completely sure of its quality. Alas, there are also unscrupulous manufacturers, in addition, product quality may suffer during improper transportation or poor storage conditions.

Many parents, striving to give their children the best from the first days of their lives, “prepare” children's water on their own. Purifying water with quality home filters allows them to be sure that the filtered water does not contain harmful chemicals and bacteria. Moreover, advanced filters enrich the water with the necessary microelements that a growing child's body needs so much. Using water purification systems, parents themselves control its quality - this gives them the opportunity not to doubt the result. Filtering water at home is somewhat similar to making fresh juice: in both cases, the consumer can follow the process and get a natural and fresh drink. Meanwhile, it is impossible to control the technological process in large-scale production, and it is not known exactly how useful such a product is.

Another benefit of using home filters is their cost-effectiveness. Water obtained by home filtration is ten times cheaper, although it is not inferior in quality to water from a supermarket, and often even surpasses it. It is suitable both for feeding the baby, and for preparing milk mixtures and cereals for him. For its natural taste and crystal purity, older children will also love it, for whom water filtered according to all the rules will also be very useful.

Water should be included in a child's diet from birth. It is vital that it undergoes thorough mechanical and biological purification and has a balanced composition of useful substances. When using bottled water, it is useful to carefully read the information on the label. As with any other product, it is advisable to take a bottle with a fresh production date. When using filtered water, keep an eye on the expiration date of the filter, clean or replace the elements of the device in a timely manner.

Water calculator

Water calculator - calculate how much water your child needs.

Water is the basis of life and a natural component of the human body. Children's bodies especially need proper water intake. After all, it is at an early age that the most important stages in the development of the nervous, circulatory, respiratory, digestive and immune systems of the body occur.

The right diet for a child is the basis of his health and further development. And the sooner you help your child form the habit of competent water consumption, the easier it will be for him to maintain a healthy and proper lifestyle in the future.

The body of a child is 80% water, and an adult is 60%. So, let's figure it out: how much water is needed for the healthy development of a child's body, what kind of water is useful, and how often should a child be offered a drink?

These and other important questions on the topic are answered by Belmer Sergey Viktorovich , Doctor of Medical Sciences, Professor of the Department of Hospital Pediatrics No. 2 of the Pediatric Faculty of the Russian National Research Medical University (RNIMU) named after. N.I. Pirogov.

Let's debunk the most popular myths about water, that is, the most popular misconceptions about its benefits, quantity, quality, and possible harm.

Myth #1: It is essential to give your baby water from the moment of birth

It's a delusion. It all depends on the specific situation, whether the child is breastfed or not. How much and how often the child consumes breast milk or formula per day. Every age has different water needs. See for yourself:

Standards for the total daily water requirement of children

The table values ​​take into account all the water that the child receives during the day. This is pure water, and various drinks, and soups, and solid food, which also contains water.

Based on the data presented in the table, you can easily calculate the child's need for clean water. So, for example, take a baby weighing 3 kilograms. According to the table, we calculate the daily need of the baby for water: 3 kg * 90 ml = 270 ml / day. If you know how much water from milk or complementary foods a child receives per day, it is not difficult to calculate whether additional water should be given to the baby.

As a rule, a breast-fed baby up to six months of age has enough water from mother's milk and does not require additional water intake. With the introduction of complementary foods, additional water is required for the child.

But once again I want to remind you that the rate of water consumption is a purely individual value, which depends on the activity of the child, the biochemical characteristics of the child's body, on the temperature and humidity of the surrounding air.

Myth #2: Bottled water should still be boiled

Bottled water does not need to be boiled. The technology of water preparation and bottling ensures its sterility throughout the entire shelf life. In this regard, boiling, aimed specifically at the destruction of microorganisms in water, is not required in this case. In all other cases, such as tap water, spring, well, etc., it is necessary to boil. And sometimes more serious methods of processing such water are required, but it is not recommended to give such water to children.

Myth #3: There is no difference between "baby" and "adult" water.

"Children's" water is distinguished by higher quality requirements and a physiologically balanced composition. Bottled water of the first and, especially, the highest category is subject to very strict requirements for its safety, in particular, for its chemical composition. In the case of "baby" water, the requirements for its composition are even higher. In its production, it is necessary not only to prevent the excess of the concentration of macro- and microelements, but also to ensure their balanced content, taking into account the characteristics of the child's body.

Myth #4: Water can be easily replaced with juices, fruit drinks and other drinks

Any drink is a source of water. However, the composition of various drinks, such as juices, fruit drinks, etc., contains other substances besides water, such as sugar, the excess of which may be undesirable for a child. In this regard, replacing “clean water” with other drinks should be done with great care. After the introduction of complementary foods, juices and fruit drinks appear in the composition of the child's diet in regulated volumes.

Myth #5: Baby water is a marketing ploy

It's a delusion. "Children's" water, as I have already said, is distinguished by special requirements for its composition, in particular, the balance of the amount of macro- and microelements, corresponding to the needs of the child's body.

Myth #6: Boiled and filtered water is no different than baby water

Boiling destroys microorganisms. The results of filtration depend on the characteristics of the filter, but, first of all, particles suspended in it are removed.

Myth #7: Water with any mineral composition is good for a child

The water contains calcium, magnesium, sodium, iodine, selenium and many other macro- and microelements that are necessary for the body. It is important that their content does not exceed the permissible concentration. On the other hand, it should be borne in mind that water is not the exclusive and even the main source of these substances: the child receives them, first of all, from other foods. However, the deficiency of certain minerals in water, which is often observed in various regions of the world, can lead to diseases. Thus, water without minerals is hazardous to health.

Myth #8: Boiled water is best for formula feeding

It's a delusion. It is best to use specially prepared industrially "baby" water. It is safe and has an optimal chemical composition.

These are the main myths about water in terms of baby food and consumption that are encountered today. For a more detailed study of the topic, consider a few more frequently asked questions that parents of babies contact us with.

What are the benefits of the minerals indicated in the composition? (Ca, Mg, K, bicarbonates, sulfates, fluorides, chlorides)

Minerals in the composition of water are necessary for the normal course of metabolic processes. Calcium and magnesium are essential for bone formation and the functioning of the nervous system, potassium is essential for the normal functioning of the heart and muscles, sodium is a key factor in almost all metabolic processes. It is very important that the chemical composition of water meets the needs of the body, which is achieved by certain technological methods in the production of special "children's" water.

How to persuade a child to drink water?

It's hard to persuade. The child drinks according to his needs. Feeling thirsty is an indicator of water intake. Water in a bottle or drinking bowl should always be nearby. Offer your baby first quality water, not sugary drinks.

How to teach a toddler to drink from a bottle?

In the first days and months of life, if necessary, you can gradually accustom the child to water, supplementing it with a spoon or from a bottle with a nipple. And if you start giving water at an older age, then you can immediately move on to a baby cup or sippy cup.

How to drink a child on a trip?

Special baby water is the best choice for a child while traveling. Such water is sterile and compensates for possible loss of salts, thanks to a balanced chemical composition.

How much baby water to take on a plane?

It depends on the age of the child and the duration of the flight, but not less than 100 ml. This is the minimum stock.

Should I give my baby water at night?

It is not necessary to water the child at night, but if such a need arises, offer the child a couple of sips of water. This is fine.

Should I give my child to drink after active games in the heat?

This must be done without fail, and not only after, but also during active games in the sun or in hot weather, since water is excreted from the body in significant quantities with sweating. Offer your baby water as often as possible. It is more convenient to take special “children's” water in a bottle for a walk, it has a small volume, but sufficient even for a two- or three-hour walk.

Children's water "FrutoNyanya" - from the first days of life!

Children's water "FrutoNyanya" is water of the highest category. Does not require boiling. The water is carefully balanced in terms of mineral composition and is suitable even for the smallest children.

FrutoNyanya special children's water is available in 0.

Choose the format that best suits you. A bottle of 0.33 liters is ideal for a walk. And for home use: preparing cereals, mixtures and pouring into a children's drinking bowl, bottled water of 1.5 liters will be convenient. A 5L canister is a great option for a large family or to take the required amount of water with you to the country.

Water quality control is carried out at all stages of the technological process of its production in the accredited testing center "FrutoNyanya". The test center employees take water samples at every stage of its production.

When extracting water from a well, the stage of water treatment, whether it is purification from mechanical impurities, the stage of normalizing the composition of water in terms of the content of macro- and microelements, the ozonation process or final filtration. Also, samples are taken without fail when pouring water into containers and its packaging.

All samples undergo mandatory testing for compliance with the requirements and standards.
