That said, I found, with my older son, that a structured environment with consistent rules are very important for him. He starts having meltdowns in environments where he doesn't know what's coming and can't anticipate change.
This is why I don't homeschool (also why I don't own my own business). DS & I are both thrive waaaaaaaaaay better within a structured environment.
JamieB - I would definitely request a meeting as well. At least you can get details of their expectations and what is happening when your child is having these issues, etc! Good luck!
