The actual height a person achieves depends on both genetic factors and personal factors. So if your parents or grandparents are short, you will get this short stature from them. There is nothing you can do about this part.
However the personal factors can be taken care of. A good balanced diet with fruits, vegetables, proteins, milk and yoghurt, cereals etc is required to be taken daily. The other thing a child can do is exercise regularly like swimming, cycling or jogging. He can do pull ups on parallel bars.
Have confidence in yourself and your abilities. Walking straight and with confidence adds an inch to your height. Always remember that height is not everything. Be happy in life.
However if the child is really very very short—say by 3-4 inches than most of your classmates, then please consult a doctor. Take care!
