B.S.
I think I would start now to mostly close the door to his room when he goes to bed. If it's still open a crack and he can see the light- he can get used to the door being mostly closed....then when he is in a bed, he won't just be looking out at you and his daddy eating popcorn!
I left my kids in crib until they were 3 at least. If they were able to climb out, I would leave the side lowered and put a chair next to the crib so they wouldn't just be jumping out--but they knew when they were supposed to be in bed.
Just an idea...you don't have to go to a big bed that soon if you don't want to yet.
(My younger sister slept in a crib until she was 6--when we finally moved into a new house and had room for another bed!)
