Telling left from right is very useful in life. Without it, we lose our sense of direction. Every parent tries to teach their young children to tell which is their right hand, and which is their left, so they can do basic things.
Many parents ask me why their children confuse right and left and how to teach them easily.
The reason children confuse between right and left can be organic (learning difficulties), emotional (stress and low emotional intelligence) or bad teaching.
