Our neighbour loves DS(4), her kids are grown up and moved out and she often brings him an ice lolly or a small toy as a treat when she feels like it.
This morning she brought him a plastic pot with "frog spawn" in it that is supposed to grow into a frog or something. It said £1.50 next to the barcode so not expensive to replace.
DS had it out in the garden in a big plastic bowl, he had been playing with it in the garden then came in for dinner, leaving the bowl and the empty pot on the windowsil outside. One of the neighbours' kids came to the door and I said I'd send him out when he'd finished eating. She was mucking about in the garden for a few minutes then never came back. DS is in bed and I've just gone to bring his toys inside, a flower the girl was carrying is lying on the windowsil and the bowl has been emptied of frog spawn and the little pot is gone. It's fairly obvious the girl (nearly 7) has taken it and she has tried to "keep" things of DS' before.
DS was quite taken on with it and excited about it growing into a frog, he's not going to be happy when he discovers it's missing in the morning. I can probably replacenit if i find out where neighbour got it, but I don't think I should need to worry about him leaving toys in his own garden without them being stolen. She'll probably be around tomorrow and I could ask her (nicely) if she borrowed it and forgot to bring it back, but from what I know of her she'll probably lie. It feels like I'm making a big deal out of such a cheap item but I don't think the value matters, she took it without asking and imo is probably old enough to know better and stealing is wrong whether the item costs a penny or a hundred pounds.
