Other countries have different parenting practices

NPR reports:

If there's one thing have in common with those , it's that they both show us just how varied parenting styles can be.

Argentine parents let their kids stay up until all hours; Japanese parents let 7-year-olds ride the subway by themselves; and Danish parents leave their kids sleeping in a stroller on the curb while they go inside to shop or eat.

Some might make American parents cringe, but others sure could use a close study. Vietnamese mothers, for instance, get their kids out of diapers by 9 months.
