I can assure you that the esame exact problem still exists in tightly knit communities. It's just that the burden is put on the grandparents or siblings. Even in those communities (I'm from one), it sucks to take care of a baby and anything that helps is used and there are tons of "oral knowledge" sort of tricks to calm down a baby or an infant. So this would still be incredibly useful regardless of how communal your life and social network is. Do you think that those communities haven't adopted the modern diaper just because hey, the community takes care of their babies together? Because that's absolutely not the case (if they can afford to).
