We interviewed 4 school principals before choosing a school for DS1, and we even had to move to get him in. Some would say that's excessive (lots of our friends have in fact), but then DS1 has some special needs and it was important to us to make things as easy for him as possible. When the first principal could offer no plans or suggestions that they would use in DS's case, and instead said "kids just need to learn to be resilient" we decided that school was out on the spot.

I think that you need to do whatever you need to do to be comfortable that you have made the right decision. If that means 1 school or 10 schools it doesn't matter. It will be different for everyone. So do whatever's right for you.

GL hun - I hope one jumps out and grabs you I totally understand how you feel.
