Re: What does your childcare/ preschool do for birthdays?
Dd's preschool did a paper crown and invited the parents to come in and read a story and/or do a craft with the kids if they wanted. I was so grateful they didn't encourage treats--dd has severe food allergies, so every in-class birthday cupcake is just another opportunity for her to feel left out.
Her kindy was also no treats. If parents wanted to celebrate in class, the teachers asked that the parent bring in a book to read and then donate the book to the classroom. I loved that! All kids really enjoyed seeing "their" birthday book in the class library.
