I knew it was coming, didnt want to see it but here we are lmao
hopefully her mom is the human one, since if her mom's the fairy then that means that either she's made out of rubber or something equally elastic, or that even if IVF was used to circumvent that specific issue then there's still the problem that if a human-fairy hybrid is still only 17cm tall, then i can only imagine how small a full-blooded fairy actually is (gonna throw out a guess and say that since she's roughly 0.1x the size of a human, then a fairy is 0.1x the size of that - meaning ~1.7cm) and if their body could even cope with the size of the half-human baby during the pregnancy.She has a human parent? How does that work exactly?
Yes, size doesn't matter.
