As it says on the title really! The thing is though he’s doing it when he thinks no one is watching and it’s normally during ‘play’ but looks really quite aggressive; I’ve caught him behaving like this a number of times recently. For example, I was watching them play in the garden today from the kitchen window and he just started randomly slapping her across the back of the head repeatedly. My daughter was fine and didn’t seem fazed, but this concerns me too - how often does he do it that I’m not aware of?
I just don’t really know how to deal with it. If it’s done in anger during an argument I can understand the motivation behind it and use tools to deescalate etc. I don’t know what is prompting what appears to be an aggressive outburst in a playful situation and other than previously telling him not to lay hands on anyone in that way and pointing out he is twice the size and strength of his sister so could really hurt her, even if he doesn’t mean to.
There have been no concerns raised by school or friends etc in terms of behaviour/violence (I’ve been told he can boisterous but this is when he’s matching classmates’ behaviour, rather than him being OTT) and he is generally a very affectionate, nice boy.
Any tips would be gratefully received!
