Nieces (DH) go to a Montessori center and for their birthday they have a "celebration of life" event where parents are welcome to participate.

This makes me wish my LO was in a Montessori center!
Our daycare will do something during snacks if you bring something in. And I know her teachers were singing Happy Birthday to all weeks before but not sure if "officially" there is anything in place.

Does your center do something similar even if it's not a Montessori center?
