Hi! I married a Vietnamese refugee, and as his relative escaped by boat to fill our entire  Boston townhouse, and have babies, I learned how they did it, and it worked in one week. They had a stick, and everytime that the one year old would mess up the floor they would hit him/her behind the knees, and somewhere around the third day they might start to sit on the toilet, yes toilet, no dumbing down for their kids, and after a few more days  of messes and fondling the toilete and trying, well by the end of a week they were making it to the toilet when they needed to go.

I, myself, could not reduce myself to such training. My son was not a rat. He wore diapers until he didn't want to anymore about 2 1/2, to the great diapprobation of my husband's family members. However, my husband was the An Hai (the eldest son of the eldest son of the eldest son and so on) sos he held great authority over his family, in spite of the fact that they did make fun of my son, still in diapers after one years old. hat, too, is too uncivilized for me, and ultimately I had totell my husband that they had better can it or go find a place to rent somewhere. And they did can it, but you could still feel it in the way they treated my son.

I recommend you let your child tell you when he is ready, and you won't have to clean up any messes, and he won't have to deal with any Freudian problems in later life. You pick your messes, you know. Diaperse are cheaper than counseling over the long term. But do what you think is best. By the way my son was an IB student and graduated college with honors; their son chose not to go to college.
