Congrats.
In case you are interested in more natural stuff, I will save you some research. Try googling ape2zebra , babynatureopathics and Vermont wooden rattle.
One thing. When a friend, family or acquaintance tells you they are expecting you go on in life and X months later you find out all was good and everybody is fine. A breeze. Not so much for the expecting couple. You worry about health. The mom can have a go of it, which means you do as well.. So it won't be a breeze, but it's life man and an incredible experience. Enjoy.
PS: if you aren't having to drive 30 clicks over the speed limit to get to the hospital in time, both of you should get a filling meal in because once you are there she can't eat and you won't eat if you know what's good for you.
