We have paired our Unicorn Warmies® with the "Little Unicorn's Birthday" Children's Book. Warmies® Board Books are a series of books designed to establish the love of reading to young children. These sturdy books feature soft, padded covers and rounded edges, making them safe for little hands to grip and hold. Snuggle up with your little one and their favorite Warmie while reading a cute story from the Warmies® Board Book Collection to introduce them to the love of books. Ages 1 year and up.
