Introducing water to infants less than six months of age is not suggested as it may adversely affect the baby. Babies who are breastfed get all the necessary liquid intake from breast milk, which is essentially 88% water. The only requisite is that the baby gets to be nursed as and when she wants. Even formula fed babies do not require water as a supplement. The baby gets all essential nutrition needed for her from breast milk and/or formula, during hot, humid days too. Breast milk and formula keep the baby hydrated enough. Many researches on the subject have been carried out, and have proven that even in summers or dry weathers, babies less than 6 months of age get all the necessary hydration from breast or formula milk and do not need water as a supplement. The only exception to this is when the baby is sick or dehydrated and is losing fluids, like if she has diarrhea. Even then, you should consult your pediatrician before offering a cool sip to your baby.
An estimation states that infants need about 1.5 mL water/kcal of energy they spend, and this ratio if found to be present in breast and formula milks. Extra liquid intake by offering extra feeds during hot weather can suffice the water requirements for infants.

Why Is It Unsafe To Give Water To Babies Younger Than 6 Months?

Giving water to a baby may reduce her body’s ability to absorb nutrients from breast milk or formula. It can affect your baby in many ways like:

• If water is given in excess it may lead to the condition of Oral water intoxication. This is a rare condition when sodium becomes diluted affecting normal body functions negatively, cause seizures and even coma
• Too much water can make the baby feel full and miss out on a feeding, without getting enough calories that the baby needs because the baby feels full
• Water also interferes with the infant’s ability to absorb the essential nutrients from breast or formula milk, interfering with the baby’s growth process
• Infants, who are given water supplements regularly, become less interested in taking their routine feeds (formula or breast milk)
• If baby is not nursing as she should, milk supply in mothers who breastfeed will get affected; since supply of breast milk is directly proportional to demand
• Water supplements keep a baby’s tummy full without increasing calories which may cause insufficient weight loss or sometimes weight gain in a baby
• Newborns can suffer an increase in bilirubin levels and get jaundice- prolonging their stay in hospitals. This also implies weight loss or gain for a baby

For any deviation, the doctor is the best person to decide.
