C.O.
I get my daycare provider a giftcard for a place to eat and have the kids make her a card.
For the teachers they get a homemade card from me and my son along with a Caribou or Starbucks giftcard.
My husband was a teacher and he always appreciated giftcards and a nice card rather than a gift he might not use. At my work my boss's wife is a teacher and after Christmas he brings in her gifts that she gets and gives them away.
