The Basics
What Is Toilet Training?

It may be training but it is not one with harsh, spartan tactics! Also, it doesn't necessarily mean your child can come off faster if you start toilet training early. After all, this isn't something he learns by being diligently taught or through harsh scolding. Doing that might even add stress to both you and your child!
 
The important thing is to react appropriately to those occasions when your child shows indications that he has an urge to pee.
 
For example, if he fidgets uncomfortably because he has peed in his diaper, calmly ask, "Did you just pee? Let's change into a new diaper to make it more comfortable", and change the diaper as you do so. When you notice that he is holding the urge, ask if he would like to go to the toilet. Keep doing things like that to show your child that going to the toilet can be a pleasant experience!
 
Although each child may start toilet training at different times, it'll be good to start to consider it when your child reaches 2 years old.
