I've read a few articles on the links between anemia in utero and early post partum and later development of autism and that is enough to convince me that my babies will be attached as long as they need to to get all the blood they need!

My boss was dangerousely anemic when pregnant and has an autistic son and I know of 4 other women who have been anemic during pregnancy and had kids with autism spectrum disorders.

It's one of those small steps you can take to help give baby the best possible start IMHO.
