Jess, what a bummer, but glad your MT/pilates teacher and her baby are doing okay!
Take it for what it is -- a chance to see what you can do on your own for a little while, or to expand your horizons and see who else is out there .... I don't know what I would do if my MT were out of commission, but I do make a point of working out with different pilates instructors -- they all have their strengths and I think I'm better off for not sticking with one person.
