What to write for the TO: on your childs Valentines day cards when you don't know the students names.?

Usually they send the list of names of your child's fellow classmates but this school for some reason didn't. My child is in pre-school, it's a small class but only talked about two other kids. What would be a good thing to write To: a fellow classmate, To: you. I just want something that isn't as lame sounding as it is.
