It is the holidays here at the moment, so we have been having preschool meet ups outside of preschool for the last two weeks. The first week 4 mums and their kids came to me. Because it is the holidays one mum brought her two older kids as well, which was fine.
The 8 year old boy wasn't particularly respectful of my house, but I kind of ignored it. When I was tidying up after, our box of hot wheels cars looked slightly less full than normal, but I don't count them in and out so didn't think anything of it.
His mum then offered for all of us to go over to hers this week. When we were getting out the of the car, out of sight of his mum, the same boy showed me three "new" cars he had got, one for him and one for his two brothers. They looked exactly like three hot wheels cars we have got, and I said so. He said they weren't ours so I left it.
When we went home I checked and our same cars had gone. I haven't found them anywhere else in the house either.
I will add as well that their mum told me that they don't have many toys as they destroy or lose them.
We see his mum every week at preschool, should I mention it, or just forget about it? I was just going to stop inviting her in the holidays and leave it at that. Its more annoying that he potentially stole, its not so much about the cars.
