I need help with our sleeping situation. My two year old currently sleeps in a crib for his nap, which is very easy since I just put him down and he falls asleep on his own. For bedtime he sleeps in a twin bed but I stay with him until he falls asleep and then in the night he usually comes to sleep in my bed. My goal is to have him sleep in his own bed, on his own, after laying him down but I don't know how to accomplish this. Do I put him back in the crib so he can cry it out contained or just take down the crib and sleep train him in the bed? We're also potty training during the day. Is this too much change for him all at once?
