Guilty. That's why I asked. What kind of physical therapy?
I can barely remember. A lot of really annoying exercises that involved trying to (this is the visual they gave my six year old self) push your belly button through to the wall. The summer before middle school, I spent hours each night curling into a ball because I convinced myself that would help. Mostly it's just consciously trying to overcorrect for a spine that wants to be extra curvy.
I'm resigned to the C shape, but know I need to do something to try to prevent the worst of the lower back problems. Pregnancy was hell on it from day one, and I'm now constantly lifting an increasingly heavy weight in the form of the kid, and the last time I threw it out, I'd been wrangling her cousin.
I should ping my SiL and ask her what it was she suggested in the way of Pilates.
