Thank you all!!!
Grinity - if I could reach through the screen and give you a big hug, I would. I LOVE the idea of the daily worksheet for the teacher. It's brilliant! I just created the form and e-mailed the school to let them know about it. I'll send 5 along in his backpack on Monday. Hopefully they will actually fill them out. If they don't.... well, all the more reason to leave the school now.
Communication with his teacher hasn't been great, and I hope this will help.
I am really leaning heavily towards pulling him out for this summer and letting him start fresh in the Fall at the new pre-K school. I just have to convince my DH. But... we'll see. Maybe we will have a big turnaround here. My son is happy and well behaved when he is home with me - so, it seems logical to keep him at home. Thank you all again, this thread has been a total sanity saver. I'm so grateful and touched that you all have taken the time to share your stories and suggestions. It means so much to me - and my husband too! THANK YOU!!!
I'll keep you all posted as things develop and as I undoubtedly need more advice.
I agree with the bolded. And I also love the daily report idea from Grinity. May just have to steal it! Hope that things improve at the school.
