If you want to improve your child's hand-eye coordination, you can buy beaded building blocks from Bao Er Animal Forest, which is a small step at home. Because this toy is both a bead and a building block, it belongs to an open toy. When playing the beading game, the baby can thread the rope into the particles, which can exercise the child's hand-eye coordination ability, develop fine movements, play with building blocks, and create various shapes. I feel that the child's hand-eye coordination ability has improved a lot after playing this toy.
