Sensory books for babies have a rich auditory and tactile experience and are more popular with babies. Each page has interesting content. The page has a built-in rattle and BB device, which can make a sound to attract the baby's attention by shaking and squeezing it, or it can make a rustling sound by turning the page. Textured 3D animal limbs help your baby develop their senses while they experience different tactile sensations and have fun.
