The Imbucare Board with Knit Ball introduces a slightly more complex posting challenge than the disc version, asking the child to maneuver a soft, yielding sphere through a circular opening in the board. This variation builds grip strength, spatial reasoning, and continued reinforcement of object permanence at the toddler level, typically for children around 10–18 months. The knit ball's texture provides additional sensory feedback, making it a useful next step in your imbucare progression after the child has mastered flat or rigid objects.
