Breast milk is a laxative and helps Gavin overcome some of the problems with constipation that has been plaguing him. We spoke to the doctor about Gavin’s constipation and she explained that it was a common problem for many toddlers because they are often too impatient to poop when they are supposed to and that causes the poop to get impacted in the bowels. Additionally, the longer the poop remains in the bowels, the more water gets reabsorped and the harder the poop becomes. Hard poop hurts and that causes toddlers to avoid the toilet even more which only serves to compound the problem. No wonder toddlers are constipated.
