gone to sleep

At last my son has gone to sleep. I told him earlier he needs to go to bed early and sleep but he never listens to me. He went to bed but he never went to sleep he was still watching cartoons until 11:00 pm. His daddy said that turn off the TV, but after a few minute he is still awake. I want to yell at him but I try not too, instead I was reading him a book. He is happy and before I could finish reading the second book about lightning McQueen (car movie) his favorite he went to sleep. I don’t like him staying awake until midnight he needs to get up early to go to school tomorrow.
