I have a 14 year old son and 9 year old daughter. Son seems to be increasingly jealous of his sister and moans constantly that I spend all my time with her. I’ve tried suggesting that me and him do things on our own together but whatever I suggest isn’t right and he refuses to come out with us as a family. When I then go out with my daughter I’m met with a torrent of abuse when I get home! Any one else have this problem and can advise?
