Progress towards mobility...

Lucas is making progress each week. Last week he was pushing up into sort of a push-up position, or "plow" pose if you're into yoga. See picture below. This week if you put your hands against his feet he uses them as leverage and pushes forward..and sometimes pops up onto all fours for a few seconds. If we place him on all fours he rocks back and forth a few times before falling on his face. I'll try to get a video later today. Why are we encouraging him??!!
