Any tips on getting my 3 year old ds to stay in bed? He's now taken to banging his head on the stairs when we tell him to go back to bed. It's 10:20pm and I started putting him to bed at 8. He's tired out, gets plenty of excercise, but fights sleep and hates being alone. DS2 is too young, I feel, at 5 months, to go in his room and I think they would disturb each other.
