M.M.
Mason is 7 months old, and we've had him on this routine since he was 3 months old. He's been a great sleeper ever since!
6:15: bath
6:25/6:30: PJs and diaper
6:35: bottle
He goes right into bed after the bottle, whether he's awake or asleep. Most of the time he's awake now. He learned to put himself to sleep doing this early on.
He either sleeps all the way through until 6:30 the next day, or he may get up once.
You have to decide what you want his routine to be, and what works best for you. I do a book at naptime, but not at night, since I don't want to turn any lights on. Bedtime for Mason has ALWAYS been in the dark.
