A child is not able to hold a crayon or marker until the toddler years, but infants are very capable of using their hands to create. Purchase some large pieces of paper and washable finger paints. Let the child mix the colors, smear them on the paper and create a picture. Hanging the picture up when the child is done will teach him to be proud of his work and will encourage further artistic self-expression.
Stacking blocks on top of one another is a milestone for infants, but aside from developing the physical ability to do this, it also teaches an infant about creating a structure or sculpture that she finds appealing. She can create these structures using whatever size, color or shape blocks she wants. Giving this freedom to create a structure is important to aesthetic development.
Music can help with aesthetic development in infants. Listening to music with your baby, dancing around with him and even giving him a musical instrument to bang on or play will teach him to make his own sounds and express himself through music.
Most of these products or toys are recommended for children who are in their preschool years. With careful supervision, allow an infant to feel the clay or Play Doh. Let her get comfortable with the texture and how it can be molded. Allow the infant to create a shape with the clay and mold it as she wishes.
