Yeah, I don't think I'd recommend a new waxer begin just before birth! Unless they had a container of MooGoo Post Wax cream
Even then, I have got an ingrown now from a wax from months ago that's been refusing to come close enough to attach...and I'm a brazilian waxer from before DS's birth! It's the first real ingrown problem I've had there since I was a teenager (had an abcessed follicle in the 'crease' that joins the thigh on the front of the pubic bone and made wearing conventional undies very uncomfy!).
