I wish that adult books had scratch and sniff options (for the most part)! Renee Khatami's LITTLE BLACK BOOK is a fun board book that will appeal to toddlers. Although it is very short, the interactive options will have young readers returning to its pages again and again. Featuring a soft bunny, smooth velvet, and spiky cat whiskers, this would be a great addition to your board book collection.
I love the interactive options--especially the scratch and sniff licorice.
