I'm afraid to say that i'm full of it...since i can remember i have chuffed my way through the day (I'm 33 now..) no matter what i eat, i think i take after my dad!!! I can remember holding it in for fear of embaressment at school, work etc. the tummy ache is horrendous. maybe some kind of peppermint homeopathic remedy might help. i have now overcome this problem by becoming self employed as a gardener and it doesn't trouble anyone. lol! i did work in a hospital and we used to blame it on the patients, oh how awful! lol at least when your daughter is at home she can get rid of it without fear of teasing. another thing make sure she chews her food properly without gulping too much air down with it. good luck and trump on!!! x
