I modified the title, because it said ggg allergy, LOL
If it was me, I deft. would avoid eggs. I really don't know if there are any studies shown that avoiding an allergy one of your child has had will decrease the chances of your next child developing it or not.
BUT.. I have heard so many mother's sware by it. Also I know some doctor's do say to avoid the common allergens while pregnant - Peanuts for sure.
If I was going to have more kids, I 100% would avoid every ounce of milk. Both of my kids had problems with milk and soy.
I say it can't hurt. Can't be for certain, but you will never know.
Hugs and CONGRATS!!! Wendy
