No worries, there are lots of exercises that can be done to help them. Practice fine motor control by using different tools such as tweezers to pick up. For example, small pom poms and move them from one bowl to another. Practice threading beads onto a pipe cleaner or building and undoing lego bricks. Once they are ready to practice with a pencil, be sure the pencil is between the index finger and thumb and then rests the pencil on the other fingers. It might also be helpful for them to use a triangular shaped pencil or gripper to start with.
