Baby gate the door . Take light bulb . Tell them it time to go to sleep . You love them and will see them in the morning . As soon as they are sleeping remove baby gate .
I made a behavior chart for my daughter one of them was staying in her bed if she followed all the rules by the end of the day she got to put a sticker on the chart at the end of the week if she had seven stickers she would get to pick a prize from the Dollar Store bag. That worked really good for us
