Congrats! Well..you're in good company...seems like half the people I know are having kids lately...whichever hospital she plans to have the baby at should give birthing classes and usually they want the father to be there too...and in the classes I think they also teach you all about what to expect through the whole process, at least from the later part of the pregnacy, through the actual birth, and the early stages of taking care of the baby...
Wonderful, Congrats!!!!! I must tell you that the best book to get is "What to Expect When You Are Expecting" It answers every question you may have. It is a must have when you are expecting!!! It is the bible of pregnancy!!!
Kids are great, there are some very hard times ahead, but trust me it is all worth it!!!
Feel free to ask any questions you may have, we have one of each and it has been so much fun!!
