Child Development

The emotional, biological and physiological changes that a human being goes through since their birth to the end of adolescence are called child development. This process is the completion of the journey where the individual progresses to increased autonomy from dependency. The reason it is called development and not growth is because growth generally refers to the individual getting bigger in size, and development refers to the various complex skills and bodily systems that the child develops as it gets older.

Child Behavior

Child behavior is a part of child development process.  It defines the way children adapt to the environment that they are living in. As children start to explore their environment, they might sometimes  behave in ways that might be somewhat annoying, but they don’t do these things purposefully. Understanding your child’s developmental milestones would help you in better understanding their behavior at various stages of their development.
