Today at a fete, a small child took a toy from my DS1 and was playing with it. I told him (pleasantly) that it was DS1's toy and asked for it back. His mother turned around from her (clearly very important) convo to at me and say "he's disabled, he don't understand." And make no attempt to take the toy from the child.
So I explained to him again that it was not his toy, found him another toy to replace it with, gave it to him and took DS1's toy away out of sight. Mother turns around and says (again) "HE'S DISABLED, HE DON'T UNDERSTAND."
OK. SO get off your bum, stop ignorning him and HELP him to understand.
Really angers me, that some people appear to think that an additional need gives them carte blanche to ignore behaviour and totally fail to apply boundaries!
