As a little girl I loved picture books and my favorite series was the Little Critter series because they were so funny and I had almost every Little Critter book made. I do remember Richard Scarry books because he had a cartoon show on Nick Jr. and the Busytown books were cute but sadly he died in 1995 but Richard Scarry picture books were adorable. You mentioned a book called Katy And The Big Snow? What's that story about? Is Katy supposed to be a snowplow and what does she do? I do believe Virginia Lee Burton also wrote a story called Choo Choo The Runaway Engine as well
