So, the first video is basically clips of Lewis army crawling and trying to rock back and forth. Pay close attention to Lewis's back, how he arches and rounds it, how his pelvis tilts, and how much his legs are involved in his movements.
Before, his body (and specifically his back) moved as a log and his legs just drug behind him. Now, his spine can twist and his pelvis can tilt and his legs play a more active role in his movements. He still has a ways go to, but these changes are huge for Lewis.
The next movie is clips of Lewis reaching. Notice what parts of his body are involved when he reaches above him.At first, Lewis used only his arm to reach above him. It got the job done. But look how, in the second part, he uses his arm, his neck, his back, and even his pelvis, to reach above him. He can reach so much higher! This may not seem like a big deal, but it will help Lewis so much to be able to effectively use every muscle he can. Think how much easier he'll be able to 4-point crawl if he can twist his spine, tilt his pelvis, and use his entire back to move his arm forward, instead of just using his arm.
I know it doesn't look like much, but these are building blocks for Lewis. I'm so excited to be able to share Lewis's hard work and progress with all of you.
Happy Mother's Day!
