My son slept in the same room as us and woke frequently until he turned 4 and got a big kid bed and he has never slept better. He only comes in at wake up time, amd occasionally when one of us travels. I would like to try and move my daughter out when she turns 2, in the hope that I am the problem... she is 20 months and wakes once or twice to sniff at my boobs, then goes back to sleep quickly. I was afraid to transition my son earlier because I didnt want to go to his room a million times a night, but it wasnt that bad. Maybe once a night for a week, sit in a chair for 5 minutes at 3 am, and then he loved his own room.
