I feel like i should probably start getting him used to the idea of sleeping in a crib but it just seems like a pain i hate the fact that if he gets uncomfortable or wakes up then i have to pick him up and rock him back to sleep and then put him down again, doing just that would surely wake him up. In his carseat and bassinet i can just rock him back to sleep but you cant with a crib cause its stationairy :/
