As I mentioned in another thread about this time period, we'd have to use sources from a century or two later and work backwards from there. That said, there's nothing from the 17th Century that would indicate that paedophilia would have been acceptable. These are, after all, societies with strong stances in opposition to child abuse, domestic abuse, and rape. Sorry that there's not much to go on here. The record is silent on the matter, which is telling, considering how much the colonists loved to rail against the comparatively liberal sexuality of Native peoples.
