When can babies drink water and how to offer it

Updated Oct 10, 2022

Drinking enough water is essential for optimal health and well-being. Babies have the largest percentage of body water, about 78% at birth. By 1 year of age, that amount drops to about 65%.  

But what does this mean for babies? Should they be drinking water throughout the day like the rest of us? The answer is — it depends! Keep reading to find out when it is appropriate to start offering your baby water and how much they need.

• Water for babies FAQ

Drinking water is important for everyone, including babies, since it has so many vital functions in the body. Water helps to carry nutrients throughout the body, lubricate joints, and regulate digestion and body temperature. As adults, we usually think of meeting our water needs by assessing the amount of water we drink each day. However, babies meet their needs a little bit differently. More on that below!

The American Academy of Pediatrics recommends introducing water for babies from the age of 6 months, although breastmilk or formula will remain their main beverage until they reach 1 year. After that, water is the best-choice beverage alongside plain cow’s or nondairy milk. 

Babies can begin to have small amounts of water when they start solids at around 6 months of age. Offer a few sips of water from an open cup or straw cup at mealtimes. Any water your baby drinks at this age is meant to get them used to its taste and introduce the skills needed for cup drinking. It is not intended to replace breastmilk or formula, which still provides all the water your baby needs. 

Babies younger than 6 months should not be offered water or any other fluids besides breastmilk or formula, which is sufficient, even on hot days. Introducing water too early or diluting formula or breastmilk with water can be dangerous for your baby because it affects the balance of electrolytes in the blood and can lead to seizures. 

Water needs may vary quite a bit from baby to baby as well as from day to day. Factors such as the weather and activity level can impact hydration needs. Additionally, high water-containing foods such as fruit, vegetables, and soup can also contribute to water intake. 

The best way to know if your baby is adequately hydrated is to watch their diapers. Babies should have at least 6 wet diapers a day to indicate they are adequately hydrated. If you aren’t seeing that, watch for other signs of dehydration and talk to your baby’s pediatrician. 

Use the table below as a general guide, and visit Healthy Drinks, Healthy Kids for more expert information from leading health organizations, such as the American Academy of Pediatrics, the Academy of Nutrition and Dietetics, and the American Heart Association.

0 - 6 months	6 - 12 months	12 - 24 months
None	4 - 8 oz	8 - 32 oz
Breastmilk and/or formula provide enough fluids.	Serve a small amount at mealtimes once solids are introduced.	Serve at meals and snacks, as well as throughout the day.

• At meals and snacks

Start by offering your baby small amounts of water at meals and snacks. This allows your baby to get used to the taste of plain water and start developing cup-drinking skills. It’s best to keep water to about 1 - 2 oz at a time, so it doesn’t displace breastmilk or formula. Stay with the lower end of the range until your baby is taking larger meals.

• In a cup

Offering water in a cup helps babies build lifelong skills such as drinking from a cup or straw. Make sure to choose appropriately-sized cups — they need to fit into small hands — and don’t be afraid to help them! Start with small amounts of water and work your way up as baby masters drinking from a cup.

• Consider foods

Fruits, vegetables, and anything that is liquid at room temperature, like soup or popsicles, all contribute to your baby’s overall water intake. Sometimes it may feel like your baby isn’t consuming a lot of liquid, but when you also take a look at their food intake, you may realize they are getting more than it appears. 

Making smoothies or popsicles at home is a fun way to offer water as well as to try new fruits and vegetables. They can be especially useful for babies who need extra calories or nutrients because you can pack a lot in a small amount of volume. 

• Throughout the day 

When your baby turns 1 year old, you can begin to have water available more frequently throughout the day. Place a cup out in the kitchen or playroom and let them know they can drink as needed.  

Dehydration can be dangerous for a baby and severe cases may require hospitalization. If you suspect your baby might be showing signs of dehydration, it’s best to call your pediatrician right away so they can guide you on what’s best to do. 

Note: conditions such as vomiting and diarrhea put your baby at increased risk for dehydration. 

According to the American Academy of Pediatrics, the following are signs of dehydration: 

Mild to moderate dehydration:

• Less activity than usual

• Less than six wet diapers a day 

• Less saliva or cracked lips

• Fewer tears when crying

• Sunken soft spot on the head

Severe dehydration (all the symptoms listed above, plus):

• Very fussy or overly sleepy

• Sunken eyes

• Cool, discolored hands and feet

• Wrinkled skin 

• Only 1 or 2 wet diapers in 24 hours

• Dry tongue and mouth

• No tears when crying

Babies can begin using a cup at about 6 months when they start to eat solids. Most feeding experts recommend starting with an open cup or a straw cup as these help to strengthen the muscles used for eating and chewing. Babies will continue to develop their cup-drinking skills through to toddlerhood.

Water for babies FAQ

Q: Can babies have too much water?

A:

Yes, babies can have too much water, and those under 6 months are at an increased risk. Once babies are eating solid foods, it is rare, but it can happen. You can avoid water intoxication in babies by following proper guidelines for introducing water and giving them an age- and activity-appropriate amount. Additionally, do not dilute formula or breastmilk with water.

Q: When can you start giving water?

A:

Babies can begin to drink small amounts of water with meals when they start solids around 6 months.

Q: Do breastfed babies need more water than formula-fed babies?

A:

No, breastmilk is about 87% water, and formula is regulated and made to resemble breast milk. So there is no reason breastfed babies would need more water than formula-fed babies. After 6 months of age, all babies who have been started on solid food should follow the same water guidelines, regardless of whether they are receiving breastmilk or formula.

Q: Is tap water bad for babies?

A:

Generally, tap water is safe for babies. However, it’s best to check to see if your tap water contains fluoride. Using fluoridated tap water to mix formula all of the time increases the risk for dental fluorosis, characterized by faint white markings on their teeth. To reduce the risk, use low- or no-fluoride bottled water to mix formula some of the time. You may also want to verify the safety of the water source before consuming it.

Q: Can babies have sparkling water or flavored water?

A:

It’s best to stick with plain water for babies. This helps them learn to like the taste of plain water before other beverages are introduced while avoiding any additives, sugar, or dissolved minerals that may not be suitable for babies.

Q: How do I know if a baby is drinking enough water?

A:

If your baby has at least 6 wet diapers a day, they are adequately hydrated. This means they are getting enough fluid (including water) from all sources: breastmilk, formula, water, and food.

Q: Is it ok if I serve water in a baby bottle?

A:

It’s best to offer baby water from a cup, if possible. This allows your baby to build important cup drinking skills and helps prevent your baby from consuming too much water. It’s easier to drink from a bottle, which may cause them to drink too much, thus displacing breastmilk, formula, or food with water unintentionally.

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.

Should I give my child bottled water?

Many young mothers are interested in the question - is it necessary to give water to a newborn baby? In this case, the doctor gives a variety of advice - some argue that breastfed babies do not need additional water, others assure the opposite. To get an answer to this question, it is necessary to understand in more detail how and when the baby should be watered, and what water can be used for this.

Mother's breast milk, which the child receives from the first days of life, is both food and drink for him - it is known that 90% of it consists of water. Thus, the breastfed baby receives all the amount of fluid he needs. Thanks to special enzymes, mother's milk has a beneficial effect on the digestion process. In addition, the female body is able to independently adapt to the needs of the baby, regulating the composition of breast milk. When the baby needs more liquid, he begins to breastfeed more, thus receiving more foremilk (it is less saturated), which not only quenches thirst well, but also restores electrolyte balance.

If we take into account all of the above, we can decide that the baby does not need ordinary water as a drink at all. But in fact, sometimes it is necessary. However, giving water to a child who is not yet three months old is possible only on the recommendation of a pediatrician. Babies who are already 4 months old can drink water - this will not affect the breastfeeding process in any way. There are absolutely no contraindications to water if the baby drinks it with pleasure. On the contrary, you should be wary of a lack of fluids, which can cause much more harm to the child. We must not forget that newborns have a very fast metabolism, due to which the loss of moisture can be very significant.

Water for baby during breastfeeding

You can give your baby water from about 4-5 months. It is best to do this not during feeding, but between them. When the baby feels thirsty, he will gladly drink water from the bottle. As for the norm of fluid for a child, this is a very individual question. As a rule, pediatricians advise giving babies about 100 mg of liquid per 1 kg of body weight, while the liquid includes breast milk. Water in this case will be from 30 to 70 ml.

The baby can drink water from an ordinary bottle with a nipple, you can also use a spoon for this (it will help to accustom the child to complementary foods, which will be needed soon). However, the main rule to remember is that the baby must drink water voluntarily, in no case should he be forced to do so.

Mixed or formula-fed baby water

Artificial feeding has significant differences from natural feeding. The fact is that infant formula contains much more protein than mother's milk. A formula-fed baby has a special need for extra fluids. If you constantly give him a rich nutrient mixture, this can cause constipation. The additional water received by the baby will improve his well-being and contribute to the normal emptying of the intestines.

If the child is on mixed or artificial feeding, then you can start giving water to him a little earlier - already from 1 or 2 months of life. In this case, the water temperature should be cooler than the temperature of the nutrient mixture. Pediatricians assure that babies who are on artificial or mixed feeding definitely need water.

You can give your baby a drink immediately after eating. You can also drink it in between feedings. It is important to remember that babies have a very small stomach in volume, and they will not physically be able to drink a lot of water. It is enough to give him 2-3 teaspoons of water. Gradually, this dose can be slightly increased.

There are situations in which the need for additional liquid for the baby increases dramatically - for example, when the child has been in a room that is too dry for a long time, or has become slightly overheated. Some parents are too afraid of catching a cold while bathing, and maintain a high temperature in his room - because of this, the humidity in the room decreases, and the baby's body is dehydrated. To prevent this from happening, the air temperature in the baby's room should be maintained at 20 degrees, and the humidity should be between 50 and 70%.

If the air in the room is too dry, the child begins to breathe rapidly, swallowing becomes difficult and colic begins. With overheating, which most often occurs in summer, the baby sweats more, as a result of which the body loses moisture. Signs of dehydration can be signs such as dry skin and mucous membranes, as well as infrequent urination. Pediatricians agree that during illness, newborns need to be given water - for example, with colic, or at elevated temperature. The water in this case should be warm.

Water is necessary for the child in such cases:

• at high temperatures - you can give him a little drink from a spoon, and just moisten his lips with water;
• with diarrhea - you need to give the child a little drink, after which it is imperative to show it to the pediatrician;
• when there is fever without temperature - water can be given to the baby in a small amount;
• for constipation - the liquid will help to empty the intestines without discomfort for the child;
• with vomiting - water will prevent dehydration and cleanse the stomach;
• for hiccups - water will relieve spasm of the diaphragm, which happened from hypothermia, and also help to get rid of excess air in the stomach.

What kind of water should a baby drink?

Some parents are sure that only boiled water can be given to babies. Actually it is not. When water is boiled, not all bacteria die in it. And in the composition of such water there are chloride compounds that are extremely harmful to babies. Water obtained from open sources can be no less dangerous, as it contains bacteria from the soil and nitrates. In no case should children be given carbonated or mineral medicinal water with a complex chemical composition. Water purified by home filters is also not suitable for babies.

Where can you get water that will not harm the child? It is best to buy it in a pharmacy. Special water for babies is labeled on the bottle, it contains the optimal amount of minerals for the baby. Water from the pharmacy does not need to be boiled, but after opening it can be stored for no more than a day, and only in the refrigerator. It is best to immediately pour such water into a glass container with a tight-fitting lid.

What methods of purifying water for a baby can be used?

The most economical and easiest option to provide your baby with high-quality drinking water is to buy a special "children's" water filter. This can be a jug-type device - it is inexpensive, it is very easy to use such a filter, and the degree of water purification is very high - the device effectively removes chlorine, bacteria, pesticides and particles of mechanical impurities from ordinary tap water. For the manufacture of such filters, only high-quality safe plastic is used, which is approved by pediatricians. Water purified in this way can be used not only for feeding the baby, but also for preparing various decoctions and infant formulas.

Can I give my baby water during hiccups?

What is hiccups? This is an involuntary contraction of the muscles of the diaphragm and larynx. Babies are especially susceptible to hiccups, since their diaphragm muscles are characterized by increased excitability. Hypothermia, air entering the stomach, nervous overexcitation and accumulation of gases in the intestines often lead to hiccups.

As soon as a child has hiccups, you need to immediately eliminate its cause. If the baby is cold, it needs to be warmed up. In order for air to come out of the stomach, the baby should be held in a “column”. A few sips of warm water will also help to cope with hiccups.

It is necessary to give water to a child with hiccups, as this measure will quickly eliminate the cause of discomfort.

If you do everything right and give water to the baby only when he really needs it, then there will be no harm - on the contrary, the child will receive the necessary amount of fluid for the normal functioning of the body.
