I just wanted to say thanks to the people who put thier input here, our 3 1/2 yr old has always had a bloated tummy and stomach cramps and I can't put my finger on excactly what causes it.
The other morning she got up and I noticed that her tummy was flat and I asked her how she felt and she said good. Well we went out for pizza that day and after we got home, what do ya know, she had a tummy ache and was all bloated. I'm gonna ask the CF doc about Miralax, hopefully it will be a solution for us.
