I did not eat any seafood while pregnant. I'm not really a seafood person.
I'm a lot more concerned about all the fire retardant that my son must have chewed off his pajamas than anything I might have eaten during pregnancy, when it comes to potential environmental aggravations.
My father was AS, as well, and his family never ate seafood.
