C.P.
I found good advice for my 6 mo old constipation on Ask Dr. Sears.com it worked for one of my kids although...my first born ended up constipated for a long long time! some kids just seem to struggle w/ it until their digestive tract develops. we ended up having to use a senna laxative for a year or so to help her pass bowel movements. the bananas and rice might be constipating...try prunes and prune juice...they work wonders for some kids. also, try feeding smaller amounts through out the day rather than all in three breakfast, lunch and dinners. ugh, it is so hard to see them struggle! good luck!
