My Lil dude decided to exit the bed stage left, and suffered a non-displaced clavicle fracture, almost in line with his neck.
This sling was great - he took to it immediately which is surprising given how much he hates being restrained for even a moment. Given he is on the small side for it we had to put a few stitches at the elbow so he couldn't work the arm free, and had to use only one strap because the other sat directly over the fracture.
Praise from both the hospital and GP on the strap.
