I agree. They generally start as close as practicable to the characters age when casting initially. However, the way the show handles character aging is hard with young actors (Hence you get a 16 year old Jared portraying a 13-14 year old Henry, which is not too bad, but is still starting to stretch believability).

Raphael Alejandro was 5-6 in Season 3 when he portrayed a 4-year-old Roland. and I would imagine that, should they ever get to the Swan story, they will cast a 5-6 year old blonde girl to portray the young Emma.
