Updates for 2018:
The most frequent monetary amount for head teachers is $50 and $25 for secondary teachers for holiday tips. Unlike K-12, parents typically give separately with two out of three (67%) giving an individual gift only.

*Last year our son was in daycare 4 days a week. There are 5 providers there. We decided on $75 per caregiver, and ultimately gave $80 per caregiver because it was easier to give all $20s.
*I've always taken approx 1 mo fees (we are part time) and divided amongst apprx 4 caregivers
I asked a while back about appropriate thank-you gifts for workers at the daycare my two-year-old attends. He's been there a bit less than six months, and is leaving at the end of the month. The upshot from the people who wrote me was: cash. The $50 range seemed to be standard."
