Something we've never seen - a little arm lift!

You might not be able to tell why we are so excited, but around 37 seconds into this video, we think we see a new shoulder movement!  He very often rolls his right arm inward with his shoulder, with his arm against his body, as you can see in the first part of the video.  When he's really mad, we've seen it be pushed inward by that muscle so hard that his arm ends up on his chest.  But here, if you go really slow-mo, you can see it slightly go outward and then up - a different shoulder muscle!!  Well, so it appears to us - any OT or PT friends want to give us their opinion? :0)  Maybe it's just the same muscle getting stronger or his back muscles, but we never see him go outward with his arm, so even slight is great!!  Another thing he's been doing lately that is new is leaving his arm on his chest after we have put it there.  Cole's OT says that this shows that he isn't just sporadically tightening his tricep to pull his arm down like he used to, and he isn't just letting it flop to his side, but somehow is helping it to stay in place.  This video is taken the day after my last post.  Thank you for your prayers!!
