I have a 9 month old and we use Colace (in liquid form.) Our dr. recommened it so you could check with yours. It doesn't work all the time and we give our fair share of enemas. Also specific foods help but you have probably already thought of that. Don't do the BRAT diet which is for diareha (Bananas, rice applesauce, toast.) For us the good foods are most fruits (esp peaches and prunes.) some veggies- gr beans. BUT NOT CARROTS (at least for us) very consitpating.
