When baby is having tummy time place the ball in front of her so she can see the colorful toy and it will stimulate her to push up and develop her reaching and grasping skills. When baby grasps the ball she can further explore it with her mouth.
To enjoy playing ball with baby while she is sitting, position yourself across from her and roll the ball to her. She will gain hand-eye coordination and reaching skills as the ball comes rolling towards her and she tries to grasp it. At this age baby is also learning how to place toys back and forth from one hand to the other. Try giving baby the ball and watch as she begins to learn how to do this. She will likely also want to put the ball in her mouth as teething is common at this stage so it is important to have an appropriate sized ball to avoid choking hazards.
