There's a new playground beside my kids school. In my opinion it is really badly laid out and part of it is fenced off from the other part, and you can't see through the fence, and due to this is very hard to completely fully watch the children. I was watching my 2 year old and when I looked up another mother was losing the plot with my older child age 7. The fence was in the way of my view. She claimed he had deliberately knocked down her child. I didn't see due to the angle, maybe he did...it would be uncharacteristic of him to have done it on purpose but I suppose possible. I took her word for it and apologised and checked that her child was ok. He was. When I turned around my child had vanished. He had run out of the playground and was hiding in some bushes trembling and shaking. I eventually got him back to the car and he curled up on the floor of it continuing to cry. A friend helped me persuade him to go back to the playground for a little bit so that he wouldn't be afraid to return the next time. He was very upset for the rest of the day and still subdued at bedtime. This woman is a parent at my children's school. I am wondering if I should speak to her and tell her the consequence of her actions as it seemed like a massive overreaction. My son was unable to tell me what she said but I think it must have been very strong as he is usually fairly thick skinned. She is part of an unfriendly clique of mums and I am afraid her reaction to him was something to do with nasty gossip between them. They are very social climber-esque and I am not good enough for them and I feel because of that it was acceptable to her to behave like that towards my child. Honestly in all the years in outdoor settings and playgrounds including during the pandemic I have never seen a parent going off on someone else's child like that. I am afraid of it happening again and we have to wait in that playground a lot as my oldest is collected from school at a later time to my 7 year old. I feel a bit powerless because it was a complete overreaction and also I have bitten my own lip so many times when bad behaviour has been directed towards my own children...the most I would ever say is 'no throwing', 'take turns' etc.
