Why do you think he was a girl back then? Just because his eyes are big and round in the thumbnail? Generally, in anime, child characters have bigger, rounder eyes to make them look cuter and more innocent, regardless of what sex they are.

Oscar has bigger eyes. The Schnee family portrait shows child Whitley with bigger eyes.

It's just a "this character is very young" thing.
