I think in both cases it's because they wanted the grown-up actors' true fairytale identities to remain somewhat of a secret. People already suspected them of being Pinocchio and Baelfire, so that make them look even more like the young child actors who originated the roles would be too big a giveaway. When casting for younger versions of roles already established, they always do a great job though.
