Exactly what I was going to respond to moes post. My wife did the same. She got so plastered during her pregnancy. I was cool with driving her and all. Didn't want her to fall down and stuff... :grin:
The real emotional burden falls on the man after the birth because any argument you present is immediately trumped by "I carried this little ****er inside of me for 9 months"
Your wife is an amazingly unselfish person. My husband pretty much quit drinking when I got pregnant; I think he only drank twice since then, on special occasions. He's being nice and suffering with me - or rather he probably doesn't want to face me going on about how unfair it is.
Breast feeding is the way to go. Let your wife do all the work while you sleep at night. No need to mess with the bottles
