My DS will be 4 months old next week and we want to start prepping for sleep training. I notice that a lot if people start doing it at this age, but can it be started if he's still sleeping in our room? I thought the AAP recommends that babies be in the parents' bedroom until 6 months? Should I start with just naps in his own room to get him uses to that and his crib? Thanks so much fellow mamas!
