Most of parents still wondered whether infants should drink water. Although mothers are warned that should not absolutely allow the infants to drink water, they still do this object as the habit. It is noticed that the baby is drunk water by his/her parents after feeding in order to clean the mouth. Perhaps, no matter what, both adults and children are also advised drinking plenty of water every day, this one is good for the body. However, with the infant, this one is entirely wrong.
