Nanny in problems

Make sure you treat them both fairly, although it does sound as though you are trying hard. Reward his good behaviour, tell him how mature he has gotten, play games, do star charts, (he gets a star on his front or forehead if he is good, I know a lot of little kid’s like these) and make sure at the end of the day, if he was all-in-all generally good, what a good boy he was and how much fun you had. (even if you didn’t) But DO NOT let him walk all over you. You have as much right to be in a room as he does. If he tells you to leave, you look him straight in the eye and say firmly “No. I belong here just as much as you do.” If it helps, you might want to get down on his level when telling him off. Make sure to never waver. If you warned him with the naughty chair, he gets the naughty chair. Also, do not just sit him down on the chair and walk away to play with the other little girl. Stay there and watch him. Make sure he clearly understands why he is in trouble. Once he is done his 10 minutes or so, ask him if he is ready to be good again like you know he can, and if he says yes, let him come down, hug him, and all is well. Do not make him feel bad, or as an outsider after his punishment. Once you have let him out of time out, he is forgiven. And never say “You are a bad boy.” He is not naturally bad. His behaviour was bad, he was acting badly. Make sure to state clearly that he was behaving badly, and that you know he can be good, because you have seen it. And if all else fails, tell the parents about his behaviour, and they can act as they see fit.
