I have just got back form the park, with my 2. dd1 is 7 (ASD), and dd2 is a very small 5.
A really quite large child (about the size of a big 15 year old - bigger than me, and I am not small! I happen to know she is younger than that, but she is a big girl) suddenly ran up, pursued by a very harassed carer, and, before either of us could stop her, hit dd2 on the top of the head. it was not light, but dd2 was not badly hurt, iyswim. she was obviously shocked.
apologies all round, and dd2 is not in the slightest bit traumatised. why? because I explained to her that the girl did not mean it personally, that she was clearly anxious and upset about something, and that sometimes, people who have difficulties find it hard to behave in some situations. all solved.
why one earth shoudl it be down to the carer to explain to dd2 (as suggested by some on the thread)? and what right do I have to demand that the other girl not be there (dd2 was in the under 6 section) - err, none.
yes, it was a shock, but if my 5 year old can understand and accept that sometimes these things happen, why are so many posters here finding it difficult?
the whole pushing/shoving thing - where were the parents of the young children? yes, I totally get the 'not being helicopter parents' thing, but surely that assessment (on the part of the parents) would change if a loud group of much larger children/teens/adults (with or without LDs) entered the park. surely there is some responsibility on the part of the parents to be explaining to the children why these adults could not wait, and maybe helping hteir children? after the hitting incident, I did not leave straightaway with my girls. I did make sure they were both closer to me, and made sure I was ready to intervene if it became necessary (it didn't). that's my job, as their mother.
the carer's in the OP do sound crap, though.
the baby on the bus situation I am also finding hard to fully understand. if I was standing with a baby in a sling, then I would just turn around, tbh. clearly if the bus was that full, then the carer and adult with LD would not have been able to move anyway, and I would have appreciated the warning so that I could keep an eye out, and be aware. I have before said similar things about dd1 - it's to keep other people fully informed and aware of the situation too. dd1 loves babies, but has, in the past, been known to be a little too over enthusiastic. I will not keep her off buses/trains/out of public places in case there is a baby and she gets excited.
I will let other people know that she may be very interested, and do my utmost to keep her away. I feel it is better for the other person to know than for it to come 'out of the blue' shoudl anythign happen. but then, sadly, it does sometimes result in the fearful glances and twitching whenever dd1 breathes...
