Luckily, when they are little, the bones heal really fast, as in 4-6 weeks. I say that as someone who shattered her lower leg in her 50s. Not a fun time at any age, but quickly over when they are little.
ps can I just say that time stood still when we had the Duke's shoulder vs Vail mountain, CO....which was only 7 months before disaster struck me. Also plates and screws for him followed up by an intractable DVT from calf to groin.
But did you decorate his cast, thatís what I want to know. ;-)
Wait , do you even get a cast with a broken shoulder?
