This was one of the books I read when Nathan was younger. Its worth checking out the chat boards because the moms post alot of great stuff and there is a nice routine that helps babies sleep. I never tried it with Nathan but when I read about it later on, the schedule was pretty much what Nathan had done naturally so it might help when kiddos are younger. http://www.thebabywhisperer.com They also have sections on products they thought were awesome and potty training and a host of other stuff.
There is also a group of woman who are really into 'wearing' their babies. The site gives you a way to buy or trade wraps, baby backpacks etc for cheap. I warn you though the woman on there are REALLY into diaper bags and baby carriers and have about 5 million a piece :) http://www.thebabywearer.com/
