Should I give a "good bye" gift to the babysitter, the way we give a gift to the teacher at the end of the school year?

My daughter’s babysitter has been babysitting several days a week since she was 7 months old, when I returned to work. It started out 3 or 4 days a week, (I forgot how many) and then I reduced it to 2 days a week, and this year, one day a week, as I increased her time at pre-school.

Today is her last day. I told her I would send her a card, and that I bought one but didn’t fill it out in time to bring it.

Should I give her a good bye gift, the way we give a gift to teachers at the end of the school year? Should it be cash or an actual gift? If you recommend cash, what is a good amount? I pay her $60 a day, FYI.
