The twos are one of child development's most confusing and exciting years. This cast of cuties demonstrate the major physical, mental, emotional developmental milestones of the third year of life. Students will witness the development of language skills, toilet training, self-awareness, and concern for others. They will learn how two-year-olds work out the contradictions of wanting both to possess and to share, to say yes and to say no, and to create and destroy.
