I agree with the other reply that suggested Baby Center. However, I kind of feel that Baby Center is more common sense stuff... if you want to learn more in depth about your child's development, you might consider a Child Development textbook. I am majoring in Family Studies right now with a strong emphasis in early childhood development. The classes are absolutely fascinating. Try half.com! It's a great place to get used textbooks for under $20. You might even be able to find some for under $5 since you wouldn't care if they are the outdated version like a student would. If you lived in my town, I'd be happy to lend you some of my old books, but I'm sure Albuquerque is a bit of a drive. ;)
