If you are not already signed up, sign up now: Baby Center http://www.babycenter.com/ This is a fun resource that sends weekly emails that tell you about the growth of your baby while pregnant and then sends weekly, short, emails after baby is born discussing what sort of things/milestones baby is likely to be doing or will be doing soon. It is not my bible by any means but more a fun, keeping me in the loop as to what a typical 5 month and 3 week old baby is doing and gives fun hints and ideas for whatever age your baby is.
Once baby gets to be about 6 months or older, I have a lot of sites I follow for play ideas and activities and for good articles on raising children... But for the first 3 months, I only really used the above.
