I am a firm believer in waking baby every 1.5 hours during the day to feed him/her. By dong this with my second, he was on a great night schedule almost immediately, and was sleeping 7 hours by 5.5 weeks.
I'd use a damp wash cloth to wake him up if he wasn't really willing. Yes, I am one of those mean mommy's who wakes a newborn. It worked great with my son, and I'm planning on doing it again with my third.
Also, make sure you wake baby at the same time every morning. I found my son would nap from 5-7, and then be up till 9ish at that age.
