My boys go to a daycare/preschool that we generally love. We switched DS1 from his first school after a few months of him getting terribly sick constantly. The class sizes are smaller at this school and we haven't had nearly the amount of illness. But I think the best part about our school is how professional the teachers all seem. They actually teach the kids (appropriate to their developmental stage) rather than just babysit. It is such a great environment for our guys! What do you like about your LO's school?
