Bonk, pause, and check

These days Joshua loves to put toys in and put toys on... whatever is around. I can put him next to the coffee table with his bucket of plastic shapes, and he will entertain himself for quite awhile by putting the shapes on the table, taking them off, and moving them around. Recently, a new little pattern of his has interfered with these moments of independent playtime. He wiggles himself along the carpet so that he is nearly underneath the coffee table. His head is right beside the table, so he bonks it. Then, Joshua takes a moment to think about what just happened and how he feels about it. After a brief pause, he looks around to see if anyone else witnessed this unfortunate event. Or is it so unfortunate? Apparently not; he proceeds to repeat the bonking!
