How much should I charge for babysitting?

Wow, you should charge more than you're getting paid for sure. At least $8 an hour. I would suggest you don't demand more without a backup plan. Ask for it first nicely and don't push it to the point that you lose your job then and there. Then, pit your current employer against other people offering you jobs. Go to SitterFinder.com . It's free and you can find other jobs in your area. I will guarantee you that you will start making more soon. And don't let her bully you into staying. She may guilt you into it, but what she is doing is not fair to you. You deserve better.
