this whole thing about recording devices creeps me out, I wouldn't be worried about our daycare activities because I know we are awesome but sometimes at nap time, I make phone calls and order stuff using my credit card number or bank info and call Dr. offices regarding private medical matters with my dd.
Sometimes I call my friend and sort of vent about my day.
Recording private phone calls is illegal and definitely an invasion of privacy.

I don't think she is recording you but you don't need this stress being 8 months pregnant. It is not good for you or the baby
