Baby food jar lids, plastic cups or kleenex boxes.
Collect the lids from baby food jars. Wash them thoroughly. Give your baby a pile of lids and an empty plastic container or a Kleenex box. Allow him to explore freely. Your baby might drop them, put them in the box or container, manipulate them with his hands or explore them with his mouth. You might talk with your baby about what you see him doing or you might do something with the lids and see if he imitates you.
Describe what you see your baby doing. “Oh, you put them in the hole and now they are in the box. Let’s shake the box and listen to hear what it sounds like.”
