Ds is 6mth. A few times when we've been out at baby groups he's had the toy he's been playing with snatched by other children. When this has happened I've tended to just find him something else to play with.
But at one group recently toys were handed out, ds was playing then a toddler of about 18mths came from the other end of the mat, took ds's toy, went back to the other end of the mat, discarded the toy and toddled off. Obviously a power thing.
There wasn't anything else for ds to play with nearby (was just 1 toy per child). It would have I thought seemed a bit ott to go to the other end of the mat to retrieve the toy. The other child's mother did nothing.
Not sure what I should do if it happens again. ds doesn't seem that bothered (just a bit surprised) but it's a bit sad for him to be left with nothing to play with.
