My nine yr old daughter has been 'trading' many of her toys in which she always gives expensive items away in exchange for 'bubble gum machine' items. When I find this out, I make her return the items and get her things back, but I think most of the time I am unaware of it, until I realize something is missing. I suspect she traded her nintendo DS, since it vanished a while back. She recently confessed when I was looking for my $400.00 heart diamond necklace, that she traded it to the 9 yr old neighbor boy for $1.00. Of course, the boy can't seem to find it, so I will not get this back. The boy's mother believes the boy, when he told her that my daughter kept pesting him for the trade. My daughter tells me that he was the one coaxing her to get the necklace. I believe her. She has been trading expensive items with this same boy quite often, in which I made her go to his house and get her items back. The mother said she was not aware of all of the trading going on. First I want to say, I thought I was a good mother. My kids never went without anything, for the most part, they have more than most of their friends have. My questions are: Why does my daughter not understand or seem to care about the value of things. Why does she continue to do this? I ground her and take her things away for punishment, but she does it again. In my opinion, I think my neighbors 9 yr old boy was wrong also, and I think they should offer to help pay for the loss. Am I wrong here? The response I got from the mother is that her children would never lie, cheat or steal, and they seem to doubt the value of my necklace, since i have no receipt. This necklace had alot of diamonds and a very good chain. I feel betrayed by my own daughter, she said she is sorry, but I really don't think she understands the value and the wrong doing. I am very stressed over this and need some good advice. Thanks!
