Toddler thinking skills includes the ability to remember things, solve problems, use imagination, reasoning, gathering, organizing and evaluating experiences. There are what are called milestones for every aspect of child development, and this includes cognitive development.

Every child moves to his own cognitive milestones at his own pace, but most toddlers demonstrate specific thinking skills around the same age range.
