Thanks everyone for all your thoughts!

I'm feeling much less stressed now.
Andrew had a great day Friday and is looking forward to tomorrow. We had some talks with him and found out some stuff that was bugging him. We talked about what to do in specific situations and to basically stay away from the kids that are being too silly. He named kids that were good listeners and were nice and we told him to basically hang out with them LOL. I guess now is a good time to talk about what makes a good friend and how to follow the golden rule. I think he felt better getting some things off his chest.
We had a meeting with the teacher and principal on Friday and got some things squared away. DH and I voiced our concerns to the teacher and principal regarding the phone call from him and long story short, it will NOT happen again. If a call needs to be made, it will be made by the teacher to us and if we feel the need to talk to him then we can. Under NO circumstances, he will not be made to call home that upset again. I was very clear about that one and I expect it to be upheld.
As far as the lunch detention, that's the K behavior plan and they'll continue to use it.

I think DS was scared straight and won't be having to do it again hopefully. I still disagree with K using lunch detention as a punishment, especially when a kid has one rough day being *silly*. We left that one as a *we'll agree to disagree* topic. She did confirm that his *silly* behavior occurred during a transition time while waiting for the rest of the kids to clean up their centers and he was asked a few times to stop and didn't. I'm still questioning lunch detention for such a small first offense and for someone so young. Rolling on the floor silly and running around being silly on the group carpet apparently equals lunch detention
That conversation led us to the class size discussion because the behavior issues are definitely a result of 29 kids, a few of which are special needs with quite a few behavior problems- hitting, spitting, etc. They will not be getting a 3rd teacher to lessen the numbers but will be getting an additional paraprofessional within the next few weeks. She will float between the 2 K's helping both teachers (one has 29 kids and the other has 28 at this point) as needed. Better than nothing I guess.
We can't afford private school. Of course I'd give up the trip to Disney and other things if we needed to but in the long run it just will strap us a little more than we can afford- especially when DD starts school in a couple years. Then we'd have to pay for two and there's no way we can make that happen. We'll just keep being involved (squeaky wheel gets the oil) and plugging away through the year as long as he still seems to like it. If he's still struggling DH has agreed that homeschooling would be our other alternative. Only 8 more months to go. First grade has 3 classes. At least that's something to look forward to.
I honestly feel bad for his teacher. She said herself that she and the para spend 90% of their day just putting out fires.

Ridiculous. This year is just one of those years I think she probably wishes would fly by. I definitely wouldn't want to be her right now. She's been teaching for 25 years so I think she was given some of the more difficult kids because she's a more seasoned teacher. That said, just because this class is an especially difficult one does not mean that my child needs to be treated so harshly for being *silly*, especially when she said herself that she's never had any issues with his behavior in the past 2 months. Wednesday was the first incident. I'm sure she doesn't like us too much right now and that's perfectly fine. As long as my child is happy and safe, I could care less how she feels about me.
Oh and you should have seen the principal's face when she talked to me with some educational jargon trying to talk above my head like I was some dummy and I threw it right back at her. She had NO idea that I used to be a teacher and have a degree in ECED! Boy, she got real quiet real quick.

It was such a good moment- even DH was like *you go girl, way to put her in her place!* when we left
