How to prevent milk from scorching while being heated?

This was one of my main problem I faced during the initial days post marraiage,the milk scorching/burning ,boiling over ,leaving a huge mess for me thereafter to tackle .A pain on my hand later !! Phew!

But now no more or say quite less (If I am careless and lazy :P )..These tips worked for me :

• Always use a tall (so that it has enough room to rise than boil over) and heavy bottomed pan/thick base not any light utensils to boil milk.
• Before using clean them with water (wet bottom) and use little water as a protective layer between the milk and the vessel.
• Boil them on medium-low heat .
• Stay near to the pan and stir constantly.
