literaticat and covertocoversf recommend bedtime books on Writer’s Voice Radio (scroll forward to 23:10 in recording).
I’m going to have to look for some of these, and not only because I have a nephew on the way in a month or two. Picture books are easily the hardest kind of book out there to write. (Anyone who doesn’t think so hasn’t actually tried.) It’s always delightful to see them done charmingly and well.
