I signed up my kids a couple months ago and they both got the book "The little Engine that Could" for their book. My son LOVES trains, so it was perfect and they both have their own copy.
They just got their 2nd book today. Bubby got "Road Work Ahead." Another perfect choice for him...it's trucks and cars!
Sissy got "What's the Big Idea Molly?"
Check to see if it is available in your area and register your children ages 0-5.
