I have 3 boys d.s.1 who is 23 and has moved out in the past but is back home at the moment.
I also have ds2 who is 8 and ds1 who is 6 but ds1 is a bully to the youngest, he allows middle son into his room to play PlayStation and listen to music but won't let the youngest in so he's left crying outside his room.
He is visibly irritated by youngest son for acting like any 6 year old child yet takes the 8 year old out buys him things and younger son is left in tears.
I have called him out and he says he doesn't mind ds2 but not ds1.
The youngest boys get on great when it's just them but when my adult ds is home he singles one out and then we have to deal with tears and tantrums.
I'm thinking about asking him to leave if he won't treat them the same,it really doesn't seem fair that he's bullied by his big brother in his own home at 6.
