Catch up on your sleep now......trust me!
Hey, unless your fiance is slamming a case of beer, mainlining nasty drugs, or bungee jumping during the pregnancy, chances are one in a million that you'll have anything to worry about. Don't forget, women have been doing this for a few millenia now, and we've got it pretty much down to a science. Best advice for the delivery? Forget everything she says during the delivery (cuz chances are it's going to be nasty and aimed at you!! :laugh: ), and don't wear any bulky rings on your hands......trust me on that one!!
Stocking up isn't a bad idea, though be careful with formula, since it does have an expiration date on it (make sure you're not buying stuff too early, ya know?). Remind your friends/relatives that gift cards to Walmart/Sam's Club/etc is just as good a present, since you can buy what you need with those. Also, let the relatives buy any expensive clothing......it's amazing, but an outfit for your baby's Christening will cost you as much as a dress for your soon to be wife! :shocked:
Finally, relax and enjoy the pregnancy. Learn that the little things you do for her during this time will put you in a lot better stance than just being the normal guy, and bragging about how you made a baby. Foot and back rubs are a definitely plus!
