Reach, grasp and release are fundamental fine motor skills. At this early stage it is important to begin to develop these skills as they are building blocks to complex fine motor skills which develop later.
Children love to place objects into containers and empty them out! This helps them to develop their grasp and release skills and refine their eye-hand coordination skills. They start with large gross movements and often miss the container. With continued practise and by making the objects and containers smaller and more complex your child will refine their release skills.
