Babies always use their strength is a normal reaction of infants, mothers do not need to worry too much. The baby’s bones are developing quickly and growing rapidly every day. If the stool color is normal and stretching to make strength, it is a sign that the body is developing. Babies often hold their faces red, which is very common in late newborn or early infancy. Some babies can get better with cod liver oil or calcium supplements, and some still do. If the baby is feeding and growing well, and there is no special physical condition, no special treatment is needed. It is recommended to give your child oral calcium gluconate supplement or more sunshine, which is good for calcium absorption.
