Renal hypoplasia
Generally, before six months, the baby's renal function development is not particularly complete. If it is unscientific to replenish plenty of water at this time, it will have a very bad influence on the baby's body.
Breast milk and milk powder contain plenty of water.
Moreover, babies six months ago are basically breast-fed or milk powder-fed, which contains a lot of water charges, and even in the dry season, there is no need to replenish a lot of water.
Appropriate increase of drinking water in complementary food.
When the baby is six months old, you can add complementary food. At this time, you can increase the amount of water, but most of the water can still be satisfied by breast milk, milk powder, fruit paste porridge and other foods, so don't feed too much water.
