I hadn't seen any of this behaviour for a while and optimistically thought it was just a phase which had passed. Then today, at a large out-of-town playground, my 5 year-old walked up to a little toddling girl and - very deliberately and entirely unprovoked - pushed her right over onto gravel. He then ran off leaving her to cry, without so much as a backwards glance.
I was absolutely furious with him, which immediately made him cry too. We've never done forced apologies but I insisted that he came over with me to see the little girl and her mum so I could tell them that I was extremely sorry and couldn't think what on earth had got into him.
I then took him home. As soon as we got in the car he told me that he wasn't sorry and that he'd done it because he 'wanted to make someone else hurt really badly.'
I didn't know quite what to say to that. I honestly cannot think why he want to make anyone else hurt. Has anyone else had experience of this?
