I think we need to figure out what's going on with the child we already have on the way before we add a third to those we need to care for. Three children is a lot to take care of, particularly if we plan on getting to any more shenanigans in the near future.
Infants don't need anything expect food. No fear, no magic. It's not much harder to protect 3 than protect one.
Besides, one of the options is to send Alice in a safe place, communicate via mirror and create second night troll enclave
Also, ifwe don't want to raise an egoist from our son, he need brothers and sisters... Jimma's baby is meant to be a slave like she is. Even if it will not get the puppet trait, it would be a weakling comparing to our son and should never be treated equally
And from roleplaying point of view it's our duty to make babies
Besides, we might come across some consort-material in the upcoming raid,
Or we might die with highly valuable unspent gift. And the left stone don't mix well with anyone who aren't very loyal
Gifts are coming at pretty steady pace, so I'd not worry with saving them
Aaaaand, many consorts are way harder to control and supply than many children. Maybe one or two more consorts is good, but more will inflate our family way to much. I prefer to make babies. Alice deserves one to lose that magical influence on her will. (plus we need to give Grandchild to Foghorn to strengthen family ties) . Gwen deserves more children because we love her and Jimma is ideal for producing second class trolls from mediocre gifts.
And if Cherlyn will stay alive, I am sure that this damned girl will seduce us at some point and will get a gift
