One-year olds sleep a lot. In their "spare time" they figure out how to use over six hundred muscles and embrace the scary task of becoming an individual. 

Physical, mental, emotional and social development intertwine as toddlers in their second year of life learn to move, think and speak in new ways. 

Watch our cast of toddlers struggle with the conflict between wanting to be independent and the desire to cling to the security of a parent and learn: 

• Different personality styles and the role of temper tantrums in emotional development. 
• The major developmental milestones of the second year of life. 
• The struggle between "I can do it myself" and "Mommy you do it." 
• The development of self-awareness and concern for others. 
• How scribbles evolve into organized forms and the child discovers the universal symbol of order a circle. 
• The growing ability of two-year-olds to follow story lines and make multi-step plans. 
• The emergence of personal agency and the realization that people influence each other's feelings. 
• How they work out contradictions between wanting to possess and to share, between yes and no, between creating and destroying.
