I believe many in this thread are fundamentally misguided. Diapers and motherhood do not mix; we require mothers to continue the species, but if we require our mothers to be padded, mating will cease, as the paternal instinct will kick in and stop proper reproduction. After all, everyone knows a true baby should be doted on and guided by a strong, caring hand. Men are obviously the strength, but women are the only ones who posses true caring; not girls, not men.
The real solution is a caste system of women: one to nurture and love, and the other to cuddle and pet. It is my dream that every man can find a beautiful maternal woman to help take care of his properly regressed little girl. The little girls are easy to spot already: they're the uppity, spoiled, infirm ones you see on "Instagram" and "Tik Tok". Truly mature women are just as common, but are often less visible due to their respectable nature.
We must institute maturity tests for women to determine which caste they fall in, and then properly assign the little girls to loving couples where they can be safe.
Obviously, there will not be enough little girls for every man. Therefore, I suggest the highly controversial practice of terminating male pregnancies (as early as possible) until the gender ratio is appropriate to make sure our sons will have one partner and one little girl. Other solutions are possible, but I feel this is the most humane.
Every poll shows this is the most popular option.
