Usage: Use the feet flash card in conjunction with the shoes and socks flash cards. This is a great sign when working with your baby toward tasks of self sufficiency such as dressing. It is also useful to equip your child to communicate pain, injury or discomfort.
As baby gets more advanced you can introduce him or her to other body parts such as arm and fingers.
