Banjo was the first thing that popped into my mind when you first posted about people checking out Board Books. Couldn't help it.

Someone actually donated a few to the Bakery as a Reading Box for kids of customers, and one of the owners pulled it after a couple of days because they were starting to get beat up. My response was mostly "Well, that's what kids of the age for these do. If they're not beat up and chewed on, that means the kids don't like that one. You can't expect 3 year-olds to treat things they love the same way an adult does."
