Hello all!
So - I emailed the school and pulled the plug for Monday (thanks CollinsMum for giving me the right words). They were very warm in their response, and have asked how they can help. I'm going to pull together ideas based on things you kind folks have offered, and a few of my own. I'll come back to this thread in the future with relevant updates, in hopes it could help others.
Meanwhile, thanks for the support. It feels great to hear words that help me believe (a) we can trust our instincts, including our son's (b) we have time to figure all this out, and we should take the time we need, and (c) there will be a way to meet his needs - even as they evolve.
Phew! I think I'll get a good night's sleep, finally. Have wonderful weekends you guys!
