Christmas Presents for Daycare Children

[Iowa daycare]

HI!
I have been doing daycare for over 6 yrs. now, and I was wondering if everyone purchased presents for daycare children?
I have every yr. that I have done daycare.
I usually spend about $10-$15.00 for each one.
SOme parents I don't even receive a thank you or nothing. Those parents, I didn't receive even a card from(which really urked me)
THen some parents will buy $1.00 candle(it's well worth the thought at least)
THen some purchase gifts and gift cards for me(what a great idea)
Just wondering if you's buy gifts, how much, and what do you receive back?
I know even a little card, to let you know you are appreciated would be great!!
