I wanted to know if accepting extra money for a babysitting job is allowed, and if not, must it be returned?
A price per hour was agreed upon. I was paid a few dollars more, most probably because it was more convenient for them to not have to worry about small change or because that was the only bills they had. In this situation, do I have to repay change if they did not ask me to?
If the money was not given because the payment to you was late, then it isn’t ribbis, and if the parent wants to give oyu extra, you are allowed to acceot it.
