Breast milk is about 90% water, and breastfed children can adjust themselves by sucking on demand if they need relatively more water, so there is no need to give breastfed children water, especially if they are under 6 months old, exclusive breastfeeding is perfectly fine and no additional water is needed. Also, when the weather is warmer, you will find that your baby tends to breastfeed more frequently, but only a few sips at a time. This way your baby is able to get more foremilk, which is richer in water and lactose, so let your baby eat more when he wants to so he can get plenty of water. Breast milk contains a lot of water, so moms don’t have to worry about their exclusively breastfed babies becoming dehydrated during the hot summer months. On the contrary, giving water to your baby too early will not only affect the amount of milk your baby eats, but will also inhibit your baby’s sucking ability, so that they will actively suck less milk from the mother’s breast and indirectly lead to less breast milk production, which is very bad for your baby’s growth. Except for special circumstances, let’s take a look at what belongs to the special circumstances: 1, sweating more inconvenient feeding: hot summer, baby sweating more, and the mother is not convenient to feed the baby, appropriate to feed the baby a little boiled water is possible. 2, when vomiting diarrhea: when the baby has vomiting, diarrhea and other phenomena, in order to avoid dehydration, you need to feed the baby the right amount of water, and at the same time should be reasonably supplemented with oral rehydration salts containing electrolytes according to the doctor’s recommendations. 3, when sick with a fever: when the baby is sick with a fever, feeding some plain water can help the baby take away the excess heat in the body, helping to cool down and reduce fever. 4, artificial or mixed feeding: In addition to exclusively breastfed babies, artificially fed or mixed-fed babies must be properly fed some plain water. After the baby has passed 6 months, it is also necessary to supplement water in appropriate amounts between meals, which is not only good for the healthy growth of the baby, but also very helpful for the future weaning of the baby. 5.After adding complementary food: After adding complementary food, you can decide whether you want to drink water with your baby’s own will. If your baby’s urine is yellow and thick, it means that your baby’s body is dehydrated and you need to give your baby timely hydration.
