In fact, even if human babies are born full term, they are indeed all considered "premature."
Normally, they should be carried for 18 to 21 months, with a birth at 21 months, to be in a similar state to newly born monkey infants.
Theoretically, the optimal gestation period for humans would be 21 months, roughly two years.
But this is something unavoidable.
Because humans have been walking upright for a long time, their legs are closer together than those of four-legged animals, and if they weren't, they simply couldn't walk steadily.
Over time, the pelvis of human females has become smaller and smaller, to the point where if the baby's head is too large, it simply cannot come out.
They are forced to sacrifice gestation time and give birth early.
But what is impossible for others is not impossible for the [Magic Goddess] or the Radiant Queen.
