I haven't filed ADA but I have disclosed in hopes of getting accomidations which only backfired on me. Because, you know, to them it's all fake or whatever.

By the way, creative, I would look into them asking you to do work while on maternity leave. I'm not sure about that. Maternity leave isn't a vacation, it's a leave of absence so that you have time to recover and bond with your baby. I would definately look into that....
