The Vest has been going okay. I will admit that hes a little on the small side for it. Not width wise, length wise. It bunches up around his neck which vibrates his head pretty good and doesn't allow him to control his neck well, so hes not a huge fan. If we try to pull it down while its running things go better, but its hard to hold onto because it shakes so much. Heres the link to a video I found on YouTube of a kid doing a Vest treatment. This kid looks like hes about two, but Drew's vest looks the same (except his is blue) and the treatment is done exactly the same way. I'll take a picture of him in it one of these days and post it. We just need a little more time to get the hang of it.
