I started the prenatals about 4 months before ttc...I figured an extra amount of the vitamins can't hurt!
I always take prenatals because I love what they do for my hair and nails. That is really interesting about the autism correlation though.
Does anyone have any suggestions for chewable pre-natal vitamins?
I slacked off on taking mine a few months after stopping BFing DS in spring of 2010 and started taking them regularly again in January, knowing that we'd plan for a baby this year. This month I added a DHA supplement as well.
