So I'm from Zambia and like in most black African cultures we carry our babies in swaddles across the back of the caregiver (like a backpack). [1]
I'm not exaggerating when I say that right this minute I can't think of a single occasion where I've ever seen a baby crying while being carried like this and most are fast asleep while the caregiver goes about their business.
