since i don't drink, etc, i didn't have to give those things up either.
also, my MIL has been hounding me about different stuff (all the news about what women should and shouldn't eat/do/etc), and with vitamins especially.
finally, i told her--"look, there are women in developing nations who have limited access to a variety of foods, are probably living sub-calorically, and also do not take prenatal vitamins. and yet their children have no birth defects and are beautiful and healthy.
so, perhaps you could just recognize that i'm eating very well, good high quality foods in good quantity, and that it's diverse and nutrient rich, and so perhaps i'll be able to have a healthy baby--just like those "poor women in other countries" who don't have the basic advantages that i do?"
she pretty much backed off now.
