I feel for you. My ds is vegan (therefore dairy-,egg-,meat-free), gluten-free, soy-free, corn-free. The soy and corn are "trials" that have been going on for at least 2 months. Recently he started having wet nights on a regular basis. For him, this has always been a sign of a food intolerance. I too can't imagine what else to remove and don't *think* he's getting contamination... I did learn that his new (began mid-June) vegan/gf multi contains some soy and corn, however his wet nights didn't begin until 7 nights ago, and he's been off the multi for 5 days now. I haven't been able to find ANY vegan, gf, corn-free, soy-free multis for children! Frustrating!
