Cutest little story!
Format: Board book
I just got this for my son and his Daddy. The story is so cute and I may have gotten choked up at the end. If you’re looking for a story for your man to read to your little one(s), I highly recommend this one!

Lovely, adorable & well-written - perfect, "daddy" book!
Format: Board book
I bought this book for my son (and maybe a little for my husband lol) when I realized he had 3 "mommy-centered" books, but none for daddy. I wanted one with quality artwork that also had a more tender and meaningful approach, rather than just silly, one that could foster appreciation of my husband and how much he loves my son. I had a difficult time narrowing down which book to get, but I am SO very glad that this is the one I went with. The pictures are adorable, the rhythm & rhyming are very well done and flow well, and the message of the book is exactly what I was hoping for, showing how daddy helps baby learn and grow and how much they love each other. My son loves it!
