Thanks all for the advice and concern and well wishes. Should probably add some key context...
Slapperina's foot injury is not a recent break or fracture, though even her surgeon thought that it was up until the point he operated on her! She experienced a freak injury in 2019...and by "freak" I mean she broke a freak bone in her foot THAT SHOULD NOT HAVE BEEN THERE! A bone we might not have ever even known about had she not had a weird slip that snapped it off. Anyway, it was operated on at the time, she had physical therapy, got better, then at the beginning of last school year, she started experiencing more pain. Took WAY longer to get operated on, but doctors kept thinking it was more about just getting bigger, faster, so she most of her freshman year in a boot or corrective shoes, on crutches, etc. Finally got operated on again beginning of summer, doctor thought he must have missed a piece of bone. Turns out the prior surgical wound healed wrong, was aggravating a tendon, made it feel like a break.
So surgery was about 2 months ago. The wound itself has healed. But now comes rehab, she hasn't used this foot properly in a year. She's still wearing the boot because she's not quite ready to put full weight on it, yet. The doctor is certain this surgery did the trick, but admittedly we won't know for sure until post-rehab.
I understand the concern about her injuring it again, but when it comes to pools, or slides, the real concern is about the discomfort she'd experience trying to get up the steps than a potential injury going down the slide. I'm a real helicopter parent most of the time, sorry to admit, but the odds of her injuring herself again, based on what was done and why...those odds are no higher than they'd be if she was just crutching around through life, as long as she takes the same precautions she always does crutching around through life
We will talk to lifeguards or a coordinator when the time comes, but my guess is if she even wants to try the slide at all (and she might not want to, just out of teenage angst of being noticed for something she doesn't want to be noticed for), it'll have to be boot off, crutches "on." And one of us with her will forgo their turn down the slide and walk back with the crutches. But if it turns out this is something the cast members have experienced and they have a better solution we'll be all ears. No pun intended. But if they also say it's too much of a liability to let her slide down at all, we won't make a stink about it either.
