Xmas present for babysitter?

lo

We started taking our one year old to a babysitter/in-home daycare about 4 months ago and it’s worked out so great! They are awesome and our little one loves them. It’s a daughter and mom who do it together. Should we get them something for Xmas? If so, what? Like just a card saying thank you and merry Xmas? I don’t want to do something over the top. Any ideas would be great since I suck at these things !
