Normally it is best to work out a schedule that suits the baby and the mother. If you really need to find some schedules then have a look at Tracey Hogg (the orignal Baby Whisperer), there are lost of discussion on the forum attached to her site about her EASY plans (Eat, Activity, Sleep, You time), these are done respecting the babies needs (well more so than other schedules out there), rather than doing too much clock watching.

I do agree with Kelly, get her a copy of Sleep like a Baby, it discusses how babies sleep, along with coping strategies.
