Ive worked at a daycare for 2.5 years now. One of the moms asked if I would be willing to babysit her 2 daughters outside of work because her daughter loves me and I'm the only person they trust. She said she's never had a babysitter and to let her know how much I charge, but I haven't babysat outside of work in so long that I have no idea. I don't want to make her pay too much but I don't wanna low ball myself either. Her kids are 4 and 11. Any suggestions?
