The names that multiple kids share at my LO's daycare are not the usual suspects. One of them is actually my LO's name, which surprises me since it was not even top 100 when we chose it. Here are the "doubles" at our small daycare (infant through toddler only):

Vivian (LO's name)
Iris (I think there are actually three of these)
Anya

What are the common names at your school or daycare?
