I know how these threads sometimes go so I'm going to start by saying that I know my ds2 is no angel and I have no objections to him being made to apologise for something he's done wrong.
When I picked up my 5yr old ds2 from school today, there was another boy (let's call him Adam) being a bit annoying, like most 5yr olds sometimes are, doing things like getting right into my ds's face and blowing on him and creeping up and shouting BOO right in his ear. I politely asked Adam to leave us alone for 5 mins and we would meet him in the playground to play for a bit. (These 2 are friends and play with each other all the time)
Ds2 and I start walking to the other classroom to collect ds1, ds2 lagging behind a bit when Adam's mum comes storming up shouting "are you X?" Ds says yes and as I'm walking back towards him, the mum is right in his face saying "what have you done to Adam? Why is he scared of you?" I calmly told the mum that I had actually just had to tell her ds to leave us alone and maybe it was 6 of one, half a dozen of the other. She stood up and back and looked a bit shocked, then agreed. We made the boys apologise to each other and warned them of the consequences of being mean and unkind to each other. All good, everyone walked away happy.
But I can't help feeling that Adam's mum was totally out of order that she felt it was appropriate to storm up to a seemingly alone 5yr old child and start shouting at him for something that may or may not have happened. She didn't realise that he was with me, she looked visibly shocked when she realised I was right there, I doubt she would have done it if she had known. Surely if she had a problem she should have gone to the teacher, not taken it upon herself to reprimand a child?
AIBU to be pissed off and want to talk to the teacher about it tomorrow? Is that over reacting, as I said once she realised I was there we sorted it out amicably but what if she tried it again to another child?
