So similarly to how Sherria's Memory Vessels work, which is why Chelia doesn't have kids yet unlike her other vessels.

So they just have to take parenthood seriously and be good mothers. Sounds rather easy to me especially since the babies should be cute and "uguu" just my little sister.

Well that's pretty cool and makes a ton of sense.
