Good job! You've hung in a situation that looked hopeless at times and now the ducks are in a row. Let's hope it works out without any more road blocks and that your dd thrives this year. If nothing else, you have them on their toes and you've brought in reinforcements so you are stronger than a parent now. You are a parent with clout. Way to go.
Keep it up. And then look for opportunities to relax and trust in what is trustworthy in the school as you all begin to heal from this while keeping on top of it.
