My 9 week old has been sleeping in her crib since she was 4 weeks old. She's done great. We have a heart beat sound that plays then shuts off automatically. We tried the bassinet in our room but she's already scooting all around and turning over, so it felt unsafe to keep her in the bassinet. She's sleeping about 6 hours at a time or sometimes all night. Best decision we made was starting early! Good luck!
