Video of Grant pulling our suitcases

Grant loves to pull and push things around. Lately he has been doing this with everything: his Little People barn, his stroller, boxes, packs of toilet paper, and anything else that he can move! Here is is pulling our suitcases in our new townhouse (he did this for almost an hour, lol). I really wonder what he is thinking sometimes. He is so focused on what he is doing that he barely even responds to us calling him or trying to get his attention, haha. He has already developed selective hearing.
