I love that you blogged about this! And I'm happy to know it's not just my kids! How many times have I told them "the food tastes the same on the blue plate as it does on the yellow plate." Yet, they STILL don't believe me. ARGH! :)
So. So. True. We have had the same problem! WHY!?!? We finally just assigned a different color to each of the kids. It helped a lot!
