The skill development in children takes place through five areas:

Cognitive Development

This is the child's ability to learn and solve problems. For example, this includes a two-month-old baby learning to explore the environment with hands or eyes or a five-year-old learning how to do simple math problems.

Social and Emotional Development

This is the child's ability to interact with others, including helping themselves and self-control. Examples of this type of development would include: a six-week-old baby smiling, a ten-month-old baby waving bye-bye, or a five-year-old boy knowing how to take turns in games at school.

Speech and Language Development

This is the child's ability to both understand and use language. For example, this includes a 12-month-old baby saying his first words, a two-year-old naming parts of her body, or a five-year-old learning to say "feet" instead of "foots".

Fine Motor Skill Development

This is the child's ability to use small muscles, specifically their hands and fingers, to pick up small objects, hold a spoon, turn pages in a book, or use a crayon to draw.

Gross Motor Skill Development

This is the child's ability to use large muscles. For example, a six-month-old baby learns how to sit up with some support, a 12-month-old baby learns to pull up to a stand holding onto furniture, and a five-year-old learns to skip.
