I have changed my name as I'm not sure whether my neighbour knows I'm on here!
There's a little girl next door who is in dd's class (yr1). She was 6 in October whereas my dd is younger. This girl is the eldest of 3 and the mother quite happily admits that the girl is her favourite child and a child who can do no wrong in her eyes (and she openly puts down her other two). Although this sounds quite odd, it's all done in a very subtle way and unless you knew the family well, you probably wouldn't pick up on it. This girl is also supremely popular at school, incredibly confident and outgoing and general always gets her own way.
Anyway, this little girl has started telling tales on dd. At a party last weekend, I picked them both up and dd was in absolute sobs. This little girl had run to the mother screaming that dd had bitten her. Dd insisted she hadn't and there were no marks on this girl (no-one had seen the incident even though everyone was in the same room which makes me think it is even more likely that it didn't happen). Because of this, dd had been ostracised by everyone else at this party (when I went in the door, the other little girls delighted in running up to me and announcing that dd was a biter!).
Essentially, even at age 6 this child is not told off at all. Dd is getting more and more stressed about this and is terrified of ever telling on this little girl when dd gets hurt by her because the girl is far quicker than dd at coming up with stories and getting dd into trouble (which she hates).
How should I get dd to deal with this?
