I often have to take things away from Henry for a variety of reasons. And, he does not like when I take things away, but he usually calms down quickly after a minute or so of complaining.
But, last night, when I too away a pint glass, Henry slapped me. He slapped me again a few minutes later and again 30 or so minutes later. I am not worried that he will hit others (yet!), but I have to make sure that he knows that this is not acceptable.
The funny thing: each time Henry slapped me, he quickly slapped something else and looked back at me as if to check for my reaction. It is incredibly interesting to watch Henry process and reflect.
