Eye-hand coordination is developed when it is obvious, visually, that a toy goes together in a particular way, for example a cube in a square hole and a sphere in a round hole. It is no small thing for a child to learn to direct her muscles to do what her eyes see should be done. And the challenge of such activities helps the child develop coordination and concentration. All of this must be considered when selecting toys for the child at this important developmental stage. The use of wood instead of plastic helps the child appreciate the natural world, the colors, shades and grains of wood, and the varying weight of wooden toys in a variety of sizes and densities.
Quality shows a respect for the child and teaches the child respect for belongings.
Beauty and durability are important at all ages for the child's tastes are being formed at this time of life. A beautiful home or a beautiful world can only be created by those who have learned to appreciate the satisfaction of living with simple, natural beauty. The first essential for the child's development is concentration. It lays the whole basis for his character and social behavior. Praise, help, or even a look, may be enough to interrupt him, or destroy the activity.
