Paying babysitter (friend)

Janna
So I'm back at work for 2wks and 2 days just to train someone for my position. A friend of mine(who is also my husband's good friend wife) is babysitting my almost 3mth old during that time for 9hrs a day. I made a decision to pay her a total of $360. Which I mentioned to my husband. 2 days later he asked about it again and he kind of freaked out. He thinks I'm paying her too much. I don't know if he wasn't paying attention or what. But I can't change it now since I confirmed it with her. He made me feel bad and i know we are a little tight on money but I thought it was a fair amount. But am I paying her too much?
