P.F.
I find the teachers much more appreciative of a toy item rather than treats. So many food allergies exist today. My son actually got a phone call thank you from a boy in his class a few years ago when I sent in a ball per child from the dollar store rather than treats. The boy said it was the first time he was not excluded from the "celebration" For me the cost was about the same.
It touched me so much that I never send treats anymore but tokens instead (tattoos, stretchy bugs etc). The Dollar Tree has lots of options. And trust me I am not one of those healthy people. I fully believe chocolate is a food group to be shared and eaten with gusto! I just don't think I ever realized how left out the kids with food allergies feel. Just my two cents--as I go eat a left over Reese's from Halloween :)
