The post on MumsNet has gone viral after a mother wrote for advice on her father’s play-fights with her son.
“My son is two and my father always plays rough with him, flinging him about onto the sofa, tickling (past the point where my son clearly can't handle it and can barely breathe), holding him upside down and he holds him by his wrists and allows him to climb up his body,” she wrote.
“I feel so powerless and " don't know how to handle this. my dad goes funny if I question anything he does and I have to really tread on eggshells with him.
“My son is starting to think I'm horrible because I'm always ruining their ‘fun’.”
It's sparked debate on whether parents should be play-fighting with their children.
Behavioural specialist Lorrine Marer says too much rough-and-tumble with kids could lead to normalising that sort of behaviour, which they could take to the playground.
However, Al Ferguson from The Dad’s Network argues play-fighting with his kids helps strengthen their bond, and and it’s important to childhood development.
