Hi M., if I were you, as someone else suggested, I'd get with the teacher and see what you can do to only invite your son's friends. The first I ever heard of this "you have to invite the whole class" thing when my kids were that age, I thought "okay, no big deal, we'll just have the party out in the yard with a bouncy house..." Ha! It was a disaster with a capital D! Most of the parents didn't even come in, and more than a few had the audacity to leave siblings as well...yes, even YOUNGER siblings! It was horrible and I would strongly urge you not to attempt it; either that, or have it at your local park and put on the invitation something to the effect of 'parents MUST stay with their child.' Even then, keep it short. (That's a lot of kids!!) Good luck, let us know what you do, V.
