Believe me, this was tough. Because my choices depend on whether I go back to my childhood, my children’s childhood or my recent reads. Elizabeth made it a bit easier by limiting our choices to pure picture books (which kept THE CAT IN THE HAT BEGINNER BOOK DICTIONARY off my list). 
4. THE STINKY CHEESE MAN –– Think both child and adult cracking up side by side on the couch. This book took “quality time” to a whole new level.
5. WHERE THE WILD THINGS ARE – WTWTA is often touted as the perfect picture book and the one to study if you’re an aspiring PB writer. I remember finding Max’s naughtiness distinctly refreshing. His smirky little face could be found on any one of my kids. This is a must-have for anyone who was once or has loved a naughty kid.
6. THE POLAR EXPRESS – My family loves trains and we love Christmas. Even though my kids are old now, we still read this every Christmas Eve out loud before we head to bed.
7. THE RUNAWAY BUNNY –– And isn’t security so important? There’s good reason children tuck themselves right into a parent’s arms when read this story.
8. MAKE WAY FOR DUCKLINGS — A charming tale in a classic city with a perfect theme – family and a mother’s love.
9. SCAREDY SQUIRREL — When I picked this one up at the ALA convention I had tears of laughter streaming down my face. 
Okay, I know Elizabeth said 10. But as soon as I sent off my list I began to have regrets for not including:
STREGA NONA – Oh gosh. I wonder where I learned the tune to “Bubble bubble pasta pot …” Did I make it up? Or did I hear Tomi sing it somewhere?
MADELINE– I received two books in the series one Christmas and instantly loved them. I remember feeling the necessity of including a collection of these stories on my own daughter’s shelf.
MIKE MULLIGAN AND THE STEAM SHOVEL – my all-time Captain Kangaroo favorite.
I really enjoy three of those on your list. I’d also add LITTLE RED CABOOSE, WHERE DOES THURSDAY GO? and DIARY OF A WOMBAT. I absolutely love those books!
Good list!
