as far as explaining this to my kids I just started by telling them "remember how mommy's tummy hurts alot" which of course they do. I then explained that different foods make my tummy hurt worse and some foods make my tummy feel better and that Im trying to eat only foods that make my tummy feel better. Eventhough its hard I also try to "hide" my discouragement about not eating my favorite foods anymore becasue I do not want my children to feel like they are doing something wrong by eating ice cream or whatever treat they have. It isn't easy and Im not sure how much my youngest understands but they all know that Mom can't eat all of the things that they do. I also explained it by saying I have to eat very healthy--(Which I try to keep them eating healthy. we have had lots of talks in the past about candy and other "junk" foods so I relate it to that as well.). How old is your daughter? Try to reassure her that you love her, if you feel up to it maybe try a quiet activity such as reading a short book or playing a quiet game (my kids like cards and I find if I sit with a heating pad, I can do that--reading is a little harder if my stomach is really hurting. You might also try having your husband talk to your daughter--have them come up with ways they could help you feel better--making a cup of peppermint tea or even drawing you a picture. My five year old knows one of his special hugs "helps" when I have a migraine.
