Yes, I've gotten a little of being thought younger too. I find that my peers can usually judge my age, but once someone is, say, about plus or minus fifteen years removed, they often can't. It's pretty strange. I think a lot of it is having a reference-- I think that's part of how people who've had kids/been around babies a lot can look at babies and estimate age, whereas I just look at babies and say "that baby is very small" or "that baby is pretty big." Or maybe that's just me.

Anyway, being in kind of an in-between age is probably pretty helpful for Chiyo. How long has she known that her father might not have been human? Not necessarily Ganma, but Other. And I'm sure someone out there has assumed that one of her unrelated uncles is the father.

Does Alain know she has a Ganma father period, or does he think it could have been some weird remnant in Kanon's body or something? And unless Ganma don't reproduce sexually at all (sexually = including things like having eggs fertilized outside the body, because my brain is weird and said hey what about sexual reproduction that doesn't require contact), Alain will probably figure it out eventually, even if it's not particularly important to him.
