He is still learning (the hard way) what he is and is not physically capable of. One day he drove into a blanket on the floor and banged his head into the wall. Another day he hit his head on an open cabinet door at daycare. He has matching bruises on his forehead (the picture below is after the bruises started fading).
Here is a short video of Reed crawling to me when I went to daycare to pick him up. Yes, he has gotten very fast at crawling already!
