life span

 To answer the following questions refer to a child that you observed from infancy to two years of age (your own child, niece/nephew, a sibling, friend's child, etc). Were you surprised about how quickly the child learned to move around, grasp objects, and otherwise explore the world? Or did the process instead seem slow? What do you wish you would had known about physical development at the time that would have helped you interact better with the infant? Is there anything you now realize about that infant’s physical development after reading the textbook and notes that you did not notice when you were watching the child grow up?
