Child development stages

Child development stages describe theoretical milestones of child development, some of which asserted as nativist theories.

This article puts forward a general model based on the most widely accepted developmental stages. However, it is important to understand that there is wide variation in terms of what is considered "normal," driven by a wide variety of genetic, cognitive, physical, family, cultural, nutritional, educational, and environmental factors. Many children will reach some or most of these milestones at different times from the norm.

Autonomy vs. Shame and Doubt (will)

(J. Chasse, 2008) Psychosocial stimulation is vital during the toddler years. Play begins to become interactive. Toddlers begin to learn and exhibit independence, but ironically they enjoy sharing this discovery with others. Another important advancement is active social play with adults including mirroring and repeating. Songs, rhymes, and finger plays (e.g. eensy weensy spider, little teapot, etc.) are a great way to encourage and stimulate this area of development. Want attention, if not paid start throwing objects, trouble with you watching TV. Scared from dark, start crying loudly under the situation.
