I just checked this book out at the library today, but so far I'm loving it. It's called The Toddler's Busy Book, written by Trish Kuffner.
She also has some great suggestions for keeping a busy toddler entertained: Keeping a "baker's box" for them to play with in the kitchen, a "rainy day" box, and a "job jar" are some of the great ideas she shares.
I'm really excited to read the rest of this book and get tons of ideas! This book is definitely worth checking out from the library or purchasing. I'm going to take good notes (I'm a super dork who does that kind of thing) but I may end up purchasing it, too.
Do you have any favorite books centered around toddler activities? I'd love to hear them in the comments below!
