Treating a child is so much different than an adult I am at a loss. I live with a torturous colon. As a 60-year-old woman, it is more difficult to live with as I age but I really work at it. Not a big believer in psychiatric drugs but that is me. I deal with it by taking Miralax daily. I get a minimum of 20 hours of exercise a week. I pay strict attention to my diet. Fiber enhancements like Metamucil make it worse for me as it tends to just build up and not pass. As I get so much exercise, and take MiraLax, drinking electrolyte beverages daily is a biggie. I also take ZenWise pre-probiotic/enzyme with each meal. That has made a huge difference in controlling bloating which is painful and got rid of the stomach issues surrounding my lack of gallbladder. Is her bilirubin normal? Mine was very low for obvious reasons. I start each day with oatmeal and for lunch, I have an apple with peanut butter. More fruit for a snack and then a normal dinner. I cook as I live remotely in the mountains and avoid processed foods. My weight tends to be on the low side to normal. Good luck with your precious daughter. When they hurt, we hurt.
