If it were me, I'd look for someone else. If it were a temporary situation, eg for the summer, etc, then I'd stick it out. In this case, her coming sounds like something to dread every other day. From what you've described, I think that's just her personality; I would doubt talking to her would change her approach (of course, you can try - you're the better judge of whether it'd be worth it). Though it's not easy to find someone good that is also a terrific match as far as personality goes, there really are excellent specialists out there. Maybe ask your pediatrician? You need someone to help you care for your son, not a supervisor to report to....
