How much should a 13 year old charge for babysitting?

I get $6 an hour from a single mom and $15 an hour from big family.
Well, first of all it depends how many kids. Here is what people usually pay me.
1 kid= 5$ an hour
2 kids= 8$ an hour
3 kids= 12$ an hour
I have never had to watch 4 kids. But i hope this helps you! Have fun babysitting!
between 20-40 a night it depends how much you do if you clean how many children how long your there that kind of stuff.maybe 6 an hour
if u are babysitting a small toddler or infant about 10 dollars an hour
and if you are babysitting a kindergartner about 4 dollars an hour
