Hi, I'm a mother of a 2 1/2 year old boy. My son has always liked a variety of foods from the beginning. Bananas are still one of his favorites. He was sick one time and I had to watch his diet, doctors orders. I thought that bananas were good for the bowels, to keep them moving, but his doctor informed me that bananas are actually constipating. Your daughter may have just been backed up. I am a massage therapist, and one suggestion for you in the future if your daughter has stomach problems like that again: Massage her stomach in a circle, clockwise(very important, counter clockwise can back her up!), from the center of the pelvis, out to the edge of the pelvis, up to the rib, over to opposite rib, down to the pelvis and back to the middle. What this does is move whatever's in the large intestine on down to the colon. You can try this on yourself first just to get a feel for it, it's really easy and definately helps. It helps with gas and constipation. Make sure you don't push too hard, but hard enough to move things, that's why I say try it on yourself first just to get a feel for how hard to push. Don't worry, you won't hurt her, if anything you will probably try not to push hard enough to avoid hurting her, she'll tell you if you are hurting her! Good luck, I hope this helps!
