The Egg with Cup (D 112) is a classic object permanence and practical life material consisting of a natural wooden egg and its corresponding cup. It is well-suited for your youngest children in the 0–3 or early 3–6 environment, supporting hand-eye coordination, pincer grip development, and the early understanding of object relationships. It's a simple, durable staple that earns its place on the infant or toddler shelf year after year.
