What you're saying goes to the heart of the article: Why are things so different in western nations compared to developing nations w.r.t. child raising? Potty training is one of the many places where we diverge wildly. Take for example Vietnam, where kids are out of diapers at around 9 months[1]. Even in the US the age at which children are potty trained has crept up slowly from 1 year to 19 months to 27 months today: > In the U.S., until the 1950s, most children were using the potty in the first few months of life and completely trained by age 1. In the 1970s, 18 months was an average age to start. Now, it's around 24 to 30 months.[2] As the article asks, what are the phenomena causing these changes and what explains the huge discrepancies between countries and cultures? Clearly the biology of children does NOT explain the difference. 1. https://www.sciencedaily.com/releases/2013/01/130130082726.htm https://www.sciencedaily.com/releases/2013/01/130130082726.h... 2. https://www.salon.com/2010/07/09/extreme_potty_training https://www.salon.com/2010/07/09/extreme_potty_training
