I have just started a shared drop of arrangement for dd1 and two friends to do an activity together. It's about 20 mins walk each way. They were lovely on the way there but on the way back all three were cheeky and ungovernable. Whining about snacks and making sullen faces when I said no we were about to have tea, saying "you're not in charge of me" when I told them to climb down off stuff and saying "I can't wait for next week when X's mummy takes us, she's way nicer than you" when I told them off for running into someone's garden. How to manage this sort of behaviour? Dd1 has lost screen time for her part in it and I have told her if I get reports of her behaving like that with other adults she is not going on any playdates, but she was no better or worse than the others.
