My 10yr old DD constantly claims to be able to do things that she can't do or to know things which she doesn't know, sometimes tipping over into elaborate lies. In a similar way she will readily cheat in games as apparently she can't bear to lose. She gets VERY upset and/or angry when I pick her up on her claims and suggest that they are not true (which I don't do too often as it seems counter-productive). -To the point that I think she may even believe them herself.
I try to reinforce the message that I love her and am proud of her just as she is and I try not to place too much emphasis on achievement in the hope that she will stop. My impression is that she doesn't feel good enough (or acceptable? or lovable?) as she is and believes that she needs constantly to court praise and approval.
I know that many, many kids go through phases of elaborating and exaggerating the truth and that it can be cute in little ones. But this is really beginning to affect her socially as it inevitably alienates her peers and she really struggles to make friends at school.
I'm shocked that she does it to me and the rest of her family all the time as we don't wish for her to be anything other than what she is. I'm worried that she doesn't trust that and that lying to me has become so habitual. It also means that she can't confide in me if she is feeling insecure.
I've tried to talk about the issue in the abstract with her, but got nowhere.
I'd be so grateful for any advice anyone might have...
