Not at all hun, I would do exactly the same in your position and being a teacher I know exactly what you mean. Depending on the area we are living in once Izzy starts school, will depend on which school she goes to and if that means that she goes to a Catholic/Independent school then so be it.

As you said, you have your kids best interest at heart, it doesn't mean that you don't believe strongly in and support the public school system. I fully support it and love working in a school that has challenging children and parents, I get frustrated by the lack of support and resources but that doesn't mean I feel any less passionate about teaching there or in any state school for that matter.

Would I send Izzy to the same school? Probably not even though I love the staff and children there!
Waffling on but hope that helps!
