DS (18 mo) was at library singing thing and was playing in a sit on train that attaches top bookcase. There was another child thee, of similar age prob slightly older (about 2).
He kicked ds twice hard in a row and as i said to him "Please don't kick" he did it again harder so I finished "it isnt friendly" (in a cherry voice not cross or very loud) as i tried to extract ds from seat, ds was at this point crying and he is a child who takes a few knocks no fuss as he has an older sister and plays at todddlers etc.
I did then manage to pick ds out of train, other mother who had her back turned picking books through this came over said something that i couldnt catch over ds crying then turned baxck to books, then turned back and said to me "Don't say that to him" complete with withering look.
I was she didnt say anything to her boy at all. I think that he must do it often as otherwise why would she immediately assume i was talking to him and not my ds? her child wasnt upset by what i said at all (he kept on trying to kick).
I didnt say anything but was bit pissed off tbh, surely if she doesnt want anyone to ever reproach her child she should be standing there watching him?
