In fact I dont believe my physio has ever sprained her ankle but she fixed mine ok.
Yeah, but the thing is an ankle is an ankle, pretty much always the same, so I'm sure it's possible to learn to fix one without actually spraining your own. Children are unique, individual human beings (as are their parents) so the idea you can apply a one-size-fits-all approach to parenting doesn't really sense. Someone who's had children (and particularly someone who's had several) will know this.
