My daughter (almost 3) was diagnosed at 10 months as anaphylactic to dairy products. She vomits, develops hives (including from contact on skin), has severe asthma episodes, stomach pains, etc. Reactions occur immediately for her, although with some of her other food allergies there is a delayed reaction of up to 5 - 6 hours. Hope this helps, Rene _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp.
