I hate to sound preachy, but I have to repeat what the others are saying: the best schedule is one that is set by mother and baby together according to their needs.

It's wonderful that you're trying to help your friend but just giving her a schedule to follow is likely to just cause distress instead of helping. For example, if I tried to follow Kellxx's scedule it would be a disaster as my baby needs 4 short sleeps instead of two long ones.

Maybe you could read the books with your friend and help explain them?
