Glitter tatoos at a day care

I've been asked to do glitter tattoos at a day care center for a child's birthday. Does anyone have any thoughts about sending home a permission/information sheet before I go?

I hate to be paranoid but since the parents aren't on site to approve their child getting a tattoo, I'd like them to notified in advance.

I plan on doing mini designs and limiting them to the back of the hand and sending a care card home with each child.

Any thoughts...

I work at an elementary school and paint the kids fairly often. I just put a sign up sheet out the day before and ask parents to put down their kid's name if it's ok to paint them. They can sign up in the morning when they bring them in or at night when they pick them up. Don't forget to send business cards home the day you paint, so parents will know who to call for the next birthday party.

Excellent idea
thank you

you can also ask the day care to get the ok from the parents. have them make a sign up sheet or you can make up one...either way would work...I did a party at a church daycare..and the mother of the birthday kids took care of letting the other parents know that I would be painting that day...
