My daughter is going to turn 3 at the end of the summer. She's been in full time daycare since she was 18 months and loves it there. She has learned a ton since she has started.

One of her classmates (she just turned 3) is leaving this daycare for a preschool. This wasn't on my radar at all... do we need to move our LO as well? What is the difference between a daycare and preschool!? Help!
