Anyway, about Mew.
A few years back various translator anons came to the conclusion that the Japanese text is just as ambiguous as "gave birth" in English. It could mean either Mew popped out the baby or a metaphor.
Of course, keep in mind that popping out babies is how IRL cloning works. Mew's body is actually more realistic than a giant tube full of orange juice.
