Ladies, lets take back some of the control..... At 15yrs of age would any of us questioned $20 per night???? I don't think so.... And it has nothing to do with inflation....it has everything to do with being greedy.
My sister works in childcare, and she also babysits on nights and weekends, charging $15 per hour - more if there are more than 2 children. I understand what you're saying, but think of it from this angle: your babysitter has agreed to look after your children, presumably play with them for a while, get them ready for bed, read to them, put them in bed, and keep an eye on them while they're sleeping. All of this generally on a Friday night or on the weekend, when teenagers generally like to go out and have a good time.

Add to that the fact that, while you can discipline you're children (whatever way you choose to discipline them), a babysitter can't - EVER. And some kids take advantage of that, and push the limits, coz they realise the babysitter can't do anything about it. I have known my sister to drop her rate when the parents get back if the kids have been really easy to look after - having a $15 per hour rate gives her the ability to be flexible, but still fair on herself if the kids end up being rotten, KWIM?
