With a regular bookshelf, I was always worrying about books falling and hitting my infant as my toddler didn't know which book to choose.  With this shelf, the toddler can pick the books he wants without a mess/danger and put them away when they are done.  Great for larger board books.  

Pros: Easy access, nice display
Cons: For small board books, they get hidden very easily so I often have to reshuffle the books so we don't lose any in the front of the pocket.
