What time do they eat lunch? And what time does school start?

LO has to be to school by 12:25, we usually leave home around 10 after, to give us enough time to get them in the car, out of the car, signed in, stuff away etc. So I find myself starting lunch around 11am, which seems pretty early to me...but otherwise there isn't time to eat and make sure she is ready to go. I'm curious what lunch looks like for other LO's who go to school in the afternoon.
