Got our niece round for a sleepover. She's lovely but a handful with it. All the dc have made an almighty mess. At one stage dn sat on the floor and kicked her legs about, spreading Lego about the whole of the kitchen/diner. Not in a tantrum (she's nearly 5) but just for the sake of it. She can be a bit destructive at times. She was mildly admonished for this and stopped. But we've been coaxing her to tidy it up since lunchtime.
We took a break and went to the park and when we came back dh and I said that all dc were to tidy and whoever did got an icecream after tea. She has refused to tidy. So our dc have had an ice-cream but she has not been allowed one. She's now sobbing in the next room. I feel bad as she is not so used to hard and fast rules at home but dh has put his foot down. Awbu?
