One of his nephews pushed their cousin a bit too hard.
Will he be punished for doing that?
No I don't think so, it was just a small angry outburst.
Pushing someone so hard is mean for a child to do. Hopefully he learns to be nicer to others.
He's only six and it seems like normal behavior for a child of that age.
Sometimes bad habits form in children of this age and any type of aggressive behavior should be discouraged. It's important to make sure he knows the difference between right and wrong.
