First of all, drinking water for a full-moon baby may cause water poisoning, which is actually not common, but if parents drink too much water for their baby, it will dilute the sodium content in the baby's body, causing edema, vomiting and even death. Secondly, the appetite of the 45-day-old baby is easily affected by drinking water, because the stomach capacity of the 45-day-old baby is very small, which will affect the normal milk intake, interfere with the normal feeding, easily lead to malnutrition of the baby and affect the normal growth and development. Moreover, the composition of water in breast milk accounts for 88%, so there is no need to replenish water to the baby.
But if you feed your baby milk powder, you can feed it properly. At the same time, if the baby has dry stool and less urine, you can also feed some warm water appropriately. If your baby has a fever or is in a state of illness, you can also add some warm water according to the situation.
