Infant art is all about the senses. At this age, they are exploring with all of their senses. I look at art class for infants as a way to allow them to explore in their own way. As they become more comfortable with materials, the infants and young toddlers aren't afraid to touch things that are messy, sticky, or cold because they've been exposed many times in different ways and at their own pace.
