The classic Chinese children’s trousers are more common in the smaller cities. In Shanghai it is almost gone, after an assault by the international diaper industry. Huggies and Pampers’ brand managers try to create an aura of modernity and progress to purchase plastic to ‘protect’ the babies’ bottoms.
The Chinese system makes all children self-regulating much faster than the literally ‘pampered’ toddlers in the west. I think this is great!
