So dd1 aged 6 had a friend over after school today. The friend was good as gold but dd and her 4 yo ds went bonkers with excitement, they were jumping off their bunk beds, pulling down their pants, tipping out box after box of toys etc. Stuff they would never normally do! I do relax the rules on playdates normally but this was just too much. I stopped them at the time obviously and had a chat with them once the friend had gone - told them that they had behaved badly and I wouldn't allow friends over in future if they did it again. They only have friends over once a month or so, hence the excitement I think. Do other people's kids get like this?! And what can I do to keep things calm next time?
