When your baby is playing on the floor, hold something reflective in front where they can see, or attach a reflective item (that is safe, and easy to attach, such as a soft toy with some reflective surfaces) on their baby gym above them.
As they move, they might notice their hands in the mirror or passing in front of them and watch them closely.
Comment if you see your baby looking at their hands to bring attention to their hands as they move them.
