When I drop off Sempi at school, I walk him to the front desk where they have name badges for the kids arranged in random order. I ask Sempi to pick out his badge while I sign the sign-in sheet. This is my way of training him to recognize his name.
This morning he told me, "Appa, do you see how the safety pin is attached sideways to my badge? I did that yesterday so I can find my badge easily in the mornings".
