Oh, that’s a tough one… I’d have to go with either Fox in Socks or One Fish Two Fish – but I’m also a big fan of The Sneetches and The Butter Battle Book. Oh, and Yertle the Turtle! There’s just too many to pick…
On a side note, has anyone read Dr. Seuss & Mr. Geisel ? I’ve been meaning to read it for years, but I haven’t gotten around to it yet – it looks like a great biography…
