The upright angle at which the book stands helps encourage play while lying on the tummy and provides the perfect reflection for the baby. It aids in the development of the baby's senses and emotional intelligence. Montessori tummy time toys strengthen the baby's leg and arm muscles to prepare for crawling, prevent flat head syndrome, and enhance hand-eye coordination. The large mirror helps the baby learn self-awareness, visual observation, and develop communication skills. Newborns prefer to look at complex high-contrast patterns, which help develop the baby's vision and stimulate their curiosity. 

The mirror is covered by the book's flaps, which can be used for a delightful peek-a-boo game between parent and baby. Star-shaped holes on the flaps covering the mirror sparkle and attract the baby's attention. It can be used in 3 different positions: on the tummy, or in a sitting position while in the stroller or when traveling by car! Lightweight and easy to fold. Made from high-quality non-toxic materials, BPA-free, PVC-free, phthalate-free.
