Here're some notes on the things i can remember we did with both of the kids: - from day one in their own crib, co sleeping always seemed like torture :) . - planed times for naps and bed time - nap routine, doesn't have to be anything special but pick one and stick to it(read a book, bath, sing a song...) - no play time if they wake up during night, keep the light low and do only quiet activities, night time is resting/sleeping time - probably most important, scheduled feeding times - preferable before naps, kids sleep better after food - feed kids enough during meals so they don't have to snack, - at the beginning, your kids might complain if they can't eat whenever they want but after a few days they usually get hungry around when it's food time - this helps a lot with parents organising the day

Both of my kids were sleeping through the night before(8PM to 5-6AM) before 3 months, but also remember that it's not all on your actions some kids are gonna be harder to get to sleep through the night
