you should have agreed on an amount before hand, and i agree with #54

No one can take advantage of you without your permission. Stop feeling sorry for yourself and grow a backbone.

When you're watching family, don't expect to be paid. Ever. If you do then you're a selfish douche bag.

you deserved it. you should have talked about payment before they left. if that's the way you conduct business, NEVER work in the real world.

Relatives aren't supposed to be paid. Geez.

YDI for expecting relatives to pay you.

I hope they at least paid for your expenses. My parents paid my cousin when she babysat us when we were little.

When I read the first five words, I knew this OP was going to be stupid. Don't say "just got done", say "just finished".

YDI if you didn't work out payment beforehand.

FYL but really if you want payment agree on that upfront before taking the kids.
