Due in large part to his cerebral palsy, Will has never truly learned how to roll over. It is a skill that he works on daily with us and his physical therapists. Because of this, we lay him on the ottoman in our living room a lot when he needs a break from sitting in his chair, we're changing his diaper, or when we just need to put him down for a minute. For the majority of his 3+ years on earth, he's always been right there when we came back.
There have been a couple of times recently when we've left Will on the ottoman, to come back a short time later and find him on the floor. Only we hadn't heard a thump, and he wasn't crying. It was very odd. But it started happening with enough consistency that we figured Will was doing it on purpose.
So I finally caught him on camera! Will appears to get himself off of the ottoman and onto the floor because he wants to... and because he knows that he can! He can do it consistently and he is VERY proud of himself when he does it. He wiggles himself to the edge of the ottoman, kicks his legs until his lower half starts moving towards the floor with the aid of gravity, and then slowly turns and lowers himself until he laying is on the floor. With a huge smile on his face.
Honestly, he's the smartest, funniest, quietest, most covert 3 year old operative I've ever seen!
