Format: Board book
This is my 2 year olds favorite book. We had to get him the rest of the authors books and this is his favorite. Highly recommended!

A Fun, Repetitive Book That Keeps Kids Engaged
Format: Board book
Dear Zoo has become a go-to read during playtime because the lift-the-flap feature keeps my baby actively involved. The simple storyline and repetition make it easy for young children to follow and anticipate what’s coming next.
Pros:
Lift-the-flap design encourages interaction and curiosity
Repetitive text helps with early language development
Short and engaging—great for babies and toddlers
Sturdy board book holds up well
Cons:
Flaps can bend if handled roughly
Very simple story, so older toddlers may outgrow it
Conclusion:
Dear Zoois a classic interactive book that works especially well for younger children.
