I start the children learning the concepts of crafting as soon as they start daycare no matter their age. Waterproof markers and fingerpaints are the best mediums for artwork. Teaching them to place stickers on paper or googly eyes on the glue with your hands on their hands takes practice but tracing their hands of painting their hands or feet and making the craft that way makes the parents happy because it's a great memento of their baby even though they might be too young to create yet.
