The GaGaGu sensory book has contrasting colors and patterns to stimulate the baby's vision. The book is double-sided. On the one hand, there are contrasting illustrations of animals with embroidered elements, which are noticeably different textures for the child under the fingers - tactile stimulation, learning different textures by the child. On the other hand, there are round plush flaps that allow the child to play one of the baby's favorite "games" - and poop! - each flap is printed on both sides with a different pattern - one element, but two completely different visual experiences. Product information (in points):• contrasting colors and patterns - stimulate the child's vision• different textures and types of materials - many sensory experiences• tails animals with different shapes and sizes - encourage catching, support of fine motor skills (finger and palm movements)• flaps under which there are paw prints - new tactile sensations
