"Photo Doodles" Wins My Vote for Best Doodle Book
I don't know if you noticed but doodle books are kind of a big thing right now.
Gabby (6) loves to draw, so I've purchased many doodle books in the hopes that they will entertain her in the car. Unfortunately, all have failed...except one. Photo Doodles by Viiiz.
I think the attraction to this doodle book specifically is that you're prompted to draw to complete real photos instead of drawings. This amused Gabby to no end and she completed every single page. That's an unprecedented completion ratio for activity books in our house!
