See that's what we are hoping for. DS1 is almost 18 and I know that eventually they get over this stage - either that or they become more adept at keeping quiet so they don't wake you!

I just feel like I shouldn't tell people that we are happy for him to play in his room all night, provided he doesn't wake us. One of the carers at childcare said her parents bought a lock for her brother's room when he was that age - it was the only way they could keep him in his room..... they would find him in the morning asleep on the floor. She said he never cried or screamed he just wanted to play so they left him to it. Probably not the recommended approach but hey, they got sleep right?!
