Gross Motor Skills As your baby lies on their tummy, they will strengthen their upper body muscles. They will learn to sit, to crawl, and eventually to walk. Tummy time is key in the development of your baby’s gross motor skills. Black & White Gymini’s engaging soft book encourages baby to extend tummy time. Fine Motor Skills Gymini’s dangling toys encourage your baby to practice their grasping skills. As your little one lies on the playmat, they will attempt to reach out to the adorable toys above their head and use their fingers to move small objects. Senses From birth, your baby aims to discover their different senses. Tiny Love’s Black & White Gymini has a black and white design with varying textures, engaging toys and musical tunes that help your baby develop these skills.
