Your baby will fall in love with the beautiful "daytime" and "nighttime" illustrations in this small and sturdy accordion book that opens to stand up in a crib, on the carpet, or in a bed, making it easy for your baby to enjoy tummy time, all the time. The daytime illustrations are black on a white background, while the nighttime illustrations are white on a black background, and with two "mirror" pages your baby can see themself and practice those future smiles! Featuring charming illustrations of babies, the sun, the moon, a star, an owl, a rooster, and more.
