6 year old doesn’t want to go to bed [Foster Care]

My wife and I got placed with three boys (7, 6, and almost 2) 5 days ago and we have issues every night with the 6 year old on going to bed. He and the 7 year old are in a room together with a bunk bed and his older brother goes to bed fine typically but he will just refuse. He’s obviously tired but not wanting to go to sleep so he sits up, climbs out of bed, tries to talk to his brother, and anything else he can think of other than going to sleep.We have been trying every trick that we know. Reading before bed, punishment (taking away tv time, not my favorite technique), telling him that he’s allowed to stay up all night if he wants but has to be quiet and in his bed (really great tactic in the past) and trying just laying in the room for a while with them. None of these have helped at all.When we ask him why he doesn’t want to go to sleep he always comes up with something that’s not really related; I want my water bottle (isn’t thirsty), it’s too dark (there’s a nightlight), I want to play with the dog (played for an hour before dinner), I don’t want to (I don’t know how to respond to that.Does anyone here have any advice on how to encourage him to go to bed at bedtime? He seems tired at night and is very difficult to wake up every morning when getting up for school, so I know he needs his sleep, but I’m not sure what to do that will help. via /r/Parenting https://ift.tt/36DXs4t
