Query: Disappointing for a Melissa & Doug Product

Let me preface this with how much I like Melissa and Doug products overall. My grandchildren have many M&D toys and this is the first that hasn't been great. It's a cute puzzle, and my grandchildren loved the animals on it, but I've never seen a puzzle where the pieces were so hard to get apart. Within the first 15 minutes of two little girls playing with the puzzle, many of the edges frayed just from trying to get the pieces apart. You might say, "They picked at the paper edges," but no, I was sitting with them and that was not the case. After two days of play, almost all the paper edges were frayed to some degree. This one will soon have to go in the trash. It's not worth my time and effort to return it.
