Since our canons no longer have a requirement and I don’t know if they ever addressed this specific issue anyway, at what point were females expected to begin covering their heads for Mass? Was there a canonical age? Up to custom? A canonical age with some customs starting earlier anyway?
This is a practical question for me as my first child (now 3 mos.) is a girl, and while I don’t expect her to start veiling soon it’s never too early to get informed for the future.
