DC are 9 and 5. They can get on sometimes but when they argue they argue A LOT. Staying in with them a nightmare. Today we went into town in the afteroon then came back. DH and I read the paper for a bit and asked the kids to play nicely. They then screamed round the house, played football, spied on us, and generally were really annoying. IMO they are too old for this behaviour and it drives me mad. They have a room of toys yet choose to play bonkers games like this all the time instead. Have read loads of parenting books and have tried various strategies but nothing seems to work. What works with your dc, and do they play nicely together?
