For the first week or so I had to sit with my son on his bed til he fell asleep, then started just waiting til he was sleepy then I'd leave his room. Eventually he knew to stay in bed when I left & he'd go to sleep. Now he goes & lays down when I play his lullaby cd or I ask him if he wants to go to bed (around his bedtime) & he'll go to his room and throw himself on his bed 😂 Just be consistent with letting him know his bed is where he needs to sleep.
