Hi, My 3 1/2 yr old daughter is asking why she needs to take enzymes and what will happen if she doesn't. We told her that it is to help the food stay in her belly and if she didn't take them she would have to go to the bathroom right away, and may have a tummy ache. She has seen a gastro in the past for reflux and the dr. explained the digestive system to her, which she repeats to us often, so we thought this was a good explanation. In the end she said she didn't understand. Has anyone else had these type of questions from a preschooler and how did you reply. I have some CF books that we read but they deal mainly with the respiratory issues, and not the digestive portion.Heather
