ok, this could be the stupidest question ever asked, but you all remember or don't *L* Brina having her knee repaired last january, at the time because of the stitches and the shaving of her entire leg/hip, my mom knit her a leg warmer/cap as I called it. What I'm wondering is this, will she have problems with it freezing this winter? will the metal plate get cold thus making her whole leg cold at times? Should I dig out the leg warmer and have her wear it when we go out? Has anyone else been through this?
