What is the ideal time to start?
It is best between the second and third birthdays, but keep in mind that, first, the little control the anal sphincter (stop pooping) and then the bladder (stop wetting).
There are parents who embark on this training within two years, something that should never be done. Unfortunately, in Western culture a lot of parents are quick with sphincter control, not let up their children.
However, there has to be previously a biological preparation with neuromuscular and psychological maturation so that everything comes to fruition.
For example, many children are afraid if they see that their stool is going down the toilet, because they are not yet prepared to understand that they are losing part of his body, but only a waste. Our society, with its concern for hygiene and cleaning, speeds up the process. Do not start too soon, nor relegate the time to start beyond the three years.
Did you decide to parent or child decides?
Somehow it’s a joint decision. Typically, parents are introduced from outside the rules and give the little the first control guidelines: bring home a little potty and propose to use that to your needs there. But the child will to decide when is going to retain or expel their feces in this new place, little by little; we will come to an agreement.
