Around the age of 4, children develop a preference for using one of their hands to complete certain tasks, like drawing for example. The same goes for foot preference, when it comes to which foot they use to start going up a flight of stairs, or to kick a ball. It even goes for our eyes and ears.

Generally when a child reaches the age of five, their preference for using one side of the body to carry out tasks is truly ingrained. This developmental process is known as right-left asymmetry. According to the US National Library of Medicine, 85-90% of adults are right-handed.
