Query: a bit disappointed

I typically love Melissa and Doug products, but I was very disappointed in this puzzle. The color on the shapes is only on the top, and the rest is just bare wood. My niece had teethed chunks of the colored paper off each shape less than half an hour after opening it. I know other M&D; puzzles are more durable, because I own a farm animal one I purchased several years back and the pieces are solid color on the front, back, and sides and have endured two children's teething just fine.Great concept, very disappointing quality. You can do better than this Melissa and Doug.
