It seems like the rules for Childling's immunity and the Enchantment rules do not have any agreement.

- There is no obvious way to fail temporary enchanting mortals.
- Permanently Enchanting mortals does not trigger Banality, it gives a dot of Banality.
Unless the rules mean: Its a dot and a trigger, and that is the one rare instance a Childling can avoid a trigger (but still gets that dot.)

Am I wrong, or am I missing some bit?
