My son is 5, and is friends with the neighbours girls who are 7 and 10. I’ve been unhappy with their friendship for a while (when they come to play they frequently push him to make bad decisions, our toys are often broken, and they treat the house like a cafe), but yesterday was a real concern. We caught him climbing over the railing of our second storey deck, allegedly to stop his friend from jumping down to the trampoline. My question is what do I do? Do I stop the friendship, should I talk to their parents, lecture them myself??
