Hiya, Poohbear,
Bottom line is - whatever you decide, is what's best for your family.
One thing that bothered me when I skimmed an article was the very down-to-earth reminder that when mom's tipsy or high on drugs, so is baby. Alcohol is technically a poison and it destroys brain cells. I don't think I'd want a poison floating around in the sea of dna and the many types of cells all trying to get together correctly with a complexity that we can't even begin to fathom.
I love this quote, whether it's true or not: It'll all be ok in the end. If it's not ok, then it's not the end.
peace, heartbeat
