Do you charge more or less to babysit?

I don’t typically babysit but I’ve had some people ask, do you charge your same rate or change it?

Edit: thank you for all your advice! Unfortunately I did tell a family my rate which is lower than my full time work, but now I know better. I always thought babysitting would pay less because I didn’t get paid much when I used to babysit years ago, and figured parents wouldn’t be okay with it but I haven’t babysat in so long and I now know that parents you want to work for will be understanding of your rates
