Dd used to be a nice, agreeable child, but the last few months, the whinging and whining has amped up considerably.
This afternoon we went out for a few hours with some friends, who included a friend of hers of the same age, and DD was in a sulk for most of the afternoon because her friend did something (fairly innocuous) and didn't say sorry.
She really spoilt the afternoon for herself (and me).
She's done similar with other friends of hers recently too.
Is this normal for a six-year-old, or something I should be coming down harder on?
She cried at the end of the afternoon because she "doesn't know why she's like that". It's very frustrating.
