👶【EARLY DEVELOPMENT】 Black and white design has been scientifically proven to help the development of rod cells in the baby's eyes. The high-contrast black and white pattern stimulates the baby's vision, increases sensitivity to things, and lays the foundation for knowing more colours in the future. 👶【NEWBORN BABY'S GROWTH】A newborn baby's brain is like a blank sheet of paper, and it takes enough sensory stimulation from the outside world for the various functions to gradually develop. By encouraging your baby's development from an early stage, you can see the progress your baby is making. Our set contains a pair of wrist rattles, a pair of sock rattles, a black and white bed surround and 20 black and white cards. ♻【SAFE & NON-TOXIC】Made of cotton-polyester material, the material is breathable and safe and non-toxic for your baby. Adjustable wrist strap and socks with elasticated mouth contain rattles, which will make a sound when the sound of shaking comes out, helping baby's hearing and voice development. The rounded corners design of the black and white card does not hurt your hands and the matte finish is not harsh.
