I know that the prevailing wisdom in child development is that kids are mostly unable to emphasize with others at this age, but I swear they must be wrong.
Henry seems to be empathetic when he knows that someone else is struggling. He gets this look on his face when he sees other crying, for example.
Henry also has a way of comforting others when they are not well. This may come in the form of a hand on the shoulder or a gift of food or a toy.
