Baby Diner is a really great product for anyone who has kids who throw plates when eating. My 18 month old son does this to tell us he is done and we make him clean the floor every night in an attempt to break him of this habit. If you want to read a review from a real mom, A Mom's Balancing Act was sent a Baby Diner to test out on her 2.5 year old.
If you go to the Baby Diner website, you can get one for free! You just have to pay shipping (it was $7.99 for me, but that is well worth it!) If you order 2, you get free shipping AND the third one free. They are normally $11.50. I can't wait to try this at our house!
