Children playing AIBU?

[Mummyofboysx]

I had taken my boys to the park the other day... 2 and 3.
My 3 year old, almost 4, is diagnosed ADD and autism. High functioning... very smart... just not great with other children. He started to interact with another child his age but does not understand sharing too well and goes over the top, hyperactive, loud and doesn't understand the needs of other kids.
He had taken this childs ball and they were both kicking it about.
When my son started to hog the ball and too over bearing to the child I was telling my son to take a breather, calm down and play nice.
The mother of the child seemed offended and kept telling my son that it was ok and he can play etc.
I really didn't feel comfortable as my child was getting more and more hyperactive and worked up. It felt like a never ending battle. I ended up leaving the park with my children resulting in both of my children crying. The next time we saw her she purposely moved away from the area.
I'm really good at controlling my son so I don't see it as a problem there.
AIBU in feeling odd about this whole situation?

She doesn’t know your sons issues and was just trying to make him feel better, though unfortunately contradicting you at the same time. I don’t see how from what you described that she was ‘offended’. It’s hard in that setting with lots of kids you don’t know and different parenting styles. She could see you were frustrated and your son too and probably thought the next time she saw you she would just avoid the whole thing from repeating.
Just forget it but if your son has a hard time interacting with others maybe a less busy play area? Or bring one of his friends along who he trusts and plays well with? Make sure you have a ball/toy to distract him with if he does the same again? You don’t want to exclude him but I can see this scenario happening again so you need a plan in place.

Sounds like she was trying to reassure you that your ds's behaviour was fine...or am I misunderstanding it?

It sounds more like she was trying to reassure you that she didn't mind what he was doing. However,you know your son and if you thought it was likely to escalate and turn bad you were right to leave, for everyone's sake including your son.

I think I may be misunderstanding this too?

Is there a chance that her not knowing your child's conditions, she thought you were helicopter parenting and she was just making sure you knew his behaviour wasn't bothering her child?
