We took Addy to an evaluation appointment today to see how she would do with forearm crutches and quad canes (wide-base "granny canes").  We started with a pair of pink canes, but they were just slightly too tall and too bulky at the base.  We moved on to a shorter pair of stainless canes.  Better fit height-wise and bulk-wise, but only 1 of the 2 canes could actually be adjusted.  Then there was the actual using of the canes.  It required just the slightest input and instruction from the PT and Addy was having a "Nope, I'm 2.5 and I'll do it my way" kind of day.
We didn't even get out the forearm crutches.  (By the end of our 1-hour appointment, she was getting the hang of it, but she wasn't real happy about it.)
Kind of bummed about that.
BUT we are now borrowing a set of 6-foot long home-made parallel bars so Addy can work on doing more of a hand-over-hand motion while she walks (which she'll need when she tries canes again).  Her PT is going to see if she can find a working pair of tiny canes for us to try at a later date.
