How do you handle kids in different schools? Also cyber-charter?

All my kids are in different schools. One goes to a a regular public brick and mortar school, one an online charter, and another a private school. We just explain each child is in the educational setting best for them at this time. There is a little of the typical sibling jealousy, but we just remind them that we have choosen the best program for each different child. With foster kids it will be a little different because you don't necessarily get to choose. However, I would just say something like,this what the judge/worker/state thinks is best for you at this time.
