M.E.
My son also has a dairy allergy and we had to wipe all dairy from his diet. Overwhelming at first, but now 6 months later he is so much healthier and happier, and it's a new way of life for all of us. It does get easier and more natural to plan meals and eating out. Check out http://godairyfree.org/ as well as search dairy free in Mamapedia. The moms here have been talking about this issue for quite some time and have helped me out a lot! My favorite thing on their website is links to restaurant menus with dairy free items. You'd be surprised what has dairy in it, and but there is a lot that doesn't-even pizza! As far as high fiber, my husband has IBS and uses metamucil and we eat lots of high fiber foods which don't affect dairy allergy at all. In fact, lots of high fiber veggies are loaded with calcium which will be good for a dairy free child. My kids have also learned to love nuts, like almonds and cashew, both high fiber and high in calcium. Good luck!
