Not my sons grandparents just to clarify but keen to here other peoples opinions. Yesterday when I was o it with DS there was a little boy about 1-18 months (I'm not good at guessing ages) with his grandparent in the soft play, he was hitting a few of the other kids if they went near him including DS, she was clearly apologetic and I told her not to worry about it as a lot of them go through this stage. He done it again to a little girl and she shouted and him and smacked his hand quite hard, not a little tap.
I was then in the park later that day and heard a grandmother threatening to smack the boys bum for trying to lift his scooter on a piece of equipment. I know of a family member who smacks granddaughters hand if she bites. I'm unsure if the parents know but I've heard and witnessed it a few other times apart from this and prior to this I really didn't think it was a thing anymore, I would never want to do this to DS despite him really pushing boundaries sometimes. I know it was more normal in the older generation but I often wonder if the parents are aware. Is this still quite commom?
