Prop up baby's tummy time exploration with the Baby Einstein Cal-a-Pillow Tummy Time Activity Pillow. Featuring Cal the Caterpillar, this soft, supportive pillow features 9 multisensory elements to engage baby, promote sensory learning, and encourage extended tummy time sessions. Baby will love to shake the triangle toy to create rattle sounds, or delight in squeezing the ladybug to make her squeak! A lift of the felt flap reveals a friendly snail, and the included mini piano entertains baby with soft, glowing lights and 20+ phrases, melodies, and sounds. A baby-safe mirror encourages self-discovery, and the pillow's crinkle leaf, 2 textured rings, and colorful, rainbow tags promote fine motor skill development. Compact design allows pillow to fit into diaper bags for discovery on-the-go. Wipes clean for easy clean-up. Requires 3 button cell batteries. Dimensions: 15.3 x 25 x 4.8 inches.
