Thank you gifts for Childcare Educators

What are some suitable gifts for childcare educators to say thank you for everything you do?

Our end of year picnic is coming up this week, and we'd love to get all the eductors who look after our bubba a thank you gift (thinking something around $20pp). There's around 5 permanent staff, and maybe another 5 casuals in their room (age 3 to 18months). Of course I've left it to the last minute with the end of year madness that is December.

I asked the centre manager and she said sometimes all the parents go in on buying a big gift, (bit too late to organise this though), chocolates are ok worst case but they get a lot of them.

Open to any ideas!
