Congratulations! So, the books are overwhelming, I agree. And everyone suggesting a book is also kind of overwhelming.....
If you are going to breastfeed, make sure you have people support, call a lactation consultant, etc.....reading a book is helpful, but talking to people is WAY more effective/supportive.
For the first 0-5 months: Happiest Baby on the Block, by Dr. Karp.
For sleeping: No Cry Sleep Solution - don't read anything else, I did, I went crazy and finally realized that kids under 2 just don't sleep regularly, ie. they have periods of waking up that come and go.
For general reference, although I had to put it away because it made me paranoid when my daughter didn't do things "on time" - Dr. Sears the First Year book
For 12-24 months: Happiest Toddler on the Block, Dr. Karp
Also, I have read some of the funny narratives about mothering that made me laugh: The Fourth Trimester; The Second Nine Months, and things like that are kind of nice to just validate what you're going through.
As for the real advice of how to be a parent, I have found the Dr. Karp books really useful as it gives actual methods, and the sleep book helped my husband, duaghter and I find a way to get enough sleep - it had different ideas/advice and really emphasized knowing your child.
Good luck, happy birth, and congratulations again!
