Constipation in Infants
Switching from breastmilk to formula causes some babies to become constipated. Call to discuss this with your doctor. Usually the stools will become soft after a few days on the formula, as your baby gets used to this new food. If it doesn't, your doctor can suggest some ways to help relieve the constipation.
Constipation is not caused by the iron that is in formula. You should never switch to a low-iron formula unless your doctor specifically tells you to do so. Iron is important for your baby's growth and development.
