Pack of 4 Sensory Balls to aid sensory tactile, visual sensory and gross/fine motor skills development, hand eye coordination. Sensory Balls enhance sensory stimulation: When children hold a sensory ball, they appreciate the nubbly texture. When they squeeze one, they can feel the rubber stretch and contract beneath their fingertips. Sensory balls are effective in massage stimulation. Softly rolling textured sensory balls on a child’s back or feet heightens sensory awareness. Sensory balls are favored by teething babies who love to chew on safe, sensory balls. Sensory Balls enhance gross motor skills: From their first months to years later children improve both fine and gross motor skills with sensory balls. Infants crawl toward sensory balls enhancing eye/hand coordination, use muscles to reach a sensory ball, then grasp and hold on tight! As children grow, they enthusiastically squeeze, roll, throw and kick sensory balls. Sensory Balls enhance socialization: Young children interact with others as they roll a sensory ball across the floor to mom and dad, grandpa or grandma. Young children eagerly toss sensory balls to playmates. Sensory Balls enhance visual and perceptual skills: Four vivid colors capture child interest. Unique projections peak visual curiosity.
