Chronic constipation and potty training? The pediatrician is not concerned in the least, and it is past time to begin potty training.  My child has to drink prune/apple juice and lots of water every day just to have a very small bowel movement every couple of days.  He is a vegetarian, who doesn't like cheese either.  So he eats mostly fruits, vegetables and whole grains (we regularly buy them).  The only protein he gets is from milk, yogurt and legumes.  I don't know, but I feel that the constipation can't be normal.  I wonder if there is something we need to do to get it checked out medically.  I am also concerned that if there is nothing medically wrong (that it's just the way he is), that the potty training is going to be difficult for him.  I have two older children, so I know how to potty train, but I think it is going to be hard for him to accomplish it.  Any advice would be welcome.

Summarized question: What causes chronic constipation in children on the vegetarian diet and how to help in potty training?
