:iagree:It can be useful to know the latest ideas on how to prevent allergies though. I have multiple allergies and sensitivities dating from since I was an infant. I knew my dc would be more likely to develop allergies. Therefore I researched allergy prevention during my pregnancy and implemented many of the things I learned. Thankfully, my dd7 does not have major allergy problems but I do not know whether that is from any action of mine or if she just inherited her father's immune system.
