Hi again,
First and foremost, my daughter drinks a lot of water...I started her on water since she was old enough to drink it. We always only serve water at the table for breakfast, lunch and dinner (it means I have to drink it too... ). I give her a lot of raw fresh veggies (carrot sticks, cucumber etc) or fruit for snacks. But you have to watch for those that are a trigger for her. My daughter is lucky, only bananas seem to bother her and only on occasion. If you decide to switch your daughter's diet now she will or course resist at first. It's normal. I found the best way to convince them is to eat the stuff yourself and not carry anything in your cupboards that is tempting. I do allow her to eat "regular" snacks...fruit roll ups, packages of real fruit gummies, even chips and stuff when she is on vacation or visiting with friends (not family, however, grammy and grampy are allowed some spoiling time too LOL). To encourage her to eat fruit, I have even bought baskets of hanging strawberries for her to pick and eat. I also bought blueberry bushes and a grape vine. Her grandparents have a garden so she frequently goes and picks her own veggies. I get her to wash to veggies for dinner so she feels part of the process and is more likely to eat the stuff if she helped preparing it. I lie to her during winter and tell her the veggies and stuff come from grampy and grammie's garden ). We also eat a lot of fish here...hallibut, sole, salmon, haddock. The specialist said I could include sprinkling bran oats (or something like that) on her cereal (only a tsp a day is required to help). Please remember if you start her on bran or anything to promote bowl movement, start in a very small amount and work your way up. Make sure she also drinks plenty of water. It will have the opposite effect if she gets too little water. I can't think of anything else right now...but will keep this in mind and write down more thoughts and post again later on. I hope this helps a little in the meantime. oh yeah, if she is fearing going to the bathroom cause of pain, you may try to teach her the deep breathing technique...it relaxes the muscles and can help her achieve the movement with less pain. Plus the more she concentrates on the breathing, the less she is concentrating on the pain.
Please let me know how you make out. The reason I am concerned and I empathize with her and you is because even now as an adult, I remember those years as a child. It's a terrible thing for a child to go through. But it can be manageable...don't give up hope okay. Keep us updated and best of luck to you. I'll be thinking of both of you.
