I don't know if it will ever be worth it but I for one wouldn't mind reading more of this takedown.
Belly.
The word is 'belly'. That's the colloquial term for the lower abdomen, and the way most children's media characterizes a pregnancy. "There's a baby in mommy's belly" as opposed to "There's a fetus developing in her uterus".
Which is an entirely different term from 'stomach', which is the organ used for digesting food. Maybe this is a weird translation issue (although it's hard to believe a translator wouldn't have picked up on the intended meaning and the fact that this implies that Sandrat, like many a Greek god, was swallowed by his parent), but I personally think it's a reasonably accurate reflection of Labelle's understanding of anatomy.
