Children learn and acquire certain habits at an early age. A child who is exposed to unhealthy habits in negative environments are capable of acting out the portrayal within his or her given surroundings.
Respectively, children also have a tendency to reflect some of their traits from what has been researched by scientists, 'genetics'. Though parents still have the responsibility to assure adequate training to each child according to his or her level of understanding and maturation, which will expel the necessary fruits from each child's behavioral pattern leading to success of their physical, mental, and social aspects in life from adolescent to adulthood years.
Of course habits learned from an early age can determine positive or negative developmental processes that regenerates his or her long-term growth in life.
