If anyone is allergic to soy, they were likely given soy formula as an
infant. Anything fed to a baby before 6 months of age is very likely to
develop allergies, because their intestines still have openings where food
can get into the blood stream. Their imune systems then treat it as an
antibody thus creating allergic reactions down the road.Giving them ANY
wheat products before 10 months-old will also cause the same problem. That's
why nursing an infant is the best thing. The longer they nurse, the less
likely they are to develop allergies as they get older. Sue Gallant
