I've name changed for this because I anticipate an onslaught for being grossly unreasonable for making anyone else's parenting my business. However, please at least put my concern in the context in which I'm asking.
I attend a toddler group with my DC. There is another boy who attends who I know is under 2. From what I've observed over a few months, he seems like a lovely, friendly little boy. I've never seen him wrestling for a toy with any of the other children or in any way become physically frustrated with them. In fact, all I ever see him do if he's not playing by himself is want to hug/be affectionate to other children, which I've also never witnessed any of the other children to reject.
The caregiver who brings him however, must shout at him at least 10 if not more times in a 2 hour period. Sometimes it's literally for being "too close" to another child (even though the child he is close to doesn't seem bothered in the slightest). Toys are snatched out of his hand by his caregiver if he goes to play with something after another child has walked away from said toy and he is reprimanded for "taking other's toys". Today he was running around and accidently ran into another running toddler; he was subsequently dragged (again, quite literally) away and when he expressed upset at this, he was shouted at, dragged into a corner and told to stay there facing the wall. I've witnessed him be slapped on the bum before at the group too.
Whilst he is not my child and the way in which he is parented is none of my business, it really does upset me the way in which he is treated. I don't intend on saying anything to the caregiver as frankly they intimidate me and as I opened with, I understand it's none of my business. I'm just not sure how to shake the feelings it brings up in me when I witness this on a weekly basis.
Generally asking for advice on how to deal with my own feelings around this as opposed to how to get involved.
Thanks.
