Since they are born, every child has continuously, clearly, and very quickly developed so that parents are very excited with such development of their child. Most parents know very well about what should be appropriate child development in each period of the child’s age. What about the inappropriate child development? How do we know that?
Some children may have development that is different from other children. If parents could not observe this, they would not know about this fact and possibly think that the development of their child would be later developed. This misunderstanding is dangerous for the child because the child’s early development in various aspects is interconnected with each other. If any aspect of the child development is slower that the others or inappropriate with the child’s age, it will affect the other aspects of child development consequentially. Therefore, parents should understand both appropriate and appropriate development of children, according to their age, simultaneously.
