Strickler’s kid and little Enrique grow up into the best of friends. It just kind of… happens. Claire and Jim are together a lot, and Strickler is always finding reasons to be around and the babies just sort of get thrown together.
Otto does all the Parent/Child matching clothes photoshoots, and will cheerfully refer to the little familiars as Mini Mes.
The babies spent the last few centuries in stasis, being cared for by goblins. They aren’t afraid when their new parent’s face changes to something more inhuman, and they giggle at magic. The Darklands changed them, just a little.
On the plus side, all these kids end up with guardians who can predict their growth spurts down to a tee because they lived them. Puberty holds no surprises. On the downside… everyone knows exactly how the kids are going to turn out.
Looks wise, at least, because personality ends up being a lot more all over the place. Cheerful Otto’s baby self is a sleepless little hellion who runs him ragged. (And then grows into the grumpiest little guy.) Nomura has a bonafide ball of sunshine on her hands, she won’t stop giggling, why won’t she stop giggling? Tiny Strickler is always bouncing off the walls and hates reading. It’s a valuable reminder that they are different people.
Most of them are stay at home parents by necessity. They don’t want to entrust their lifeline to daycare, or risk some supernatural danger coming to their magic touched kids. Even Strickler takes a break, cashes in some of his savings, and focuses on full time parenting and part time changeling organization management. (They schedule Skype calls around naps.) He’ll go back to work when the baby is old enough to be in school. A few of the changelings who are married to humans (a complicated enough endeavor on it’s own, since most of those relationships have some, uh, fundamental issues) and have a little bit more backup negotiate part-time positions.
Nomura loves her museum and refuses to give it up, so she gets a baby carrier and does archival work with an infant tugging on her hair. Baby Nomura accidentally swallows a few roman coins when she gets old enough to toddle, but otherwise the arrangement works.
It helps that Draal comes over a lot at night and is excellent at baby soothing. In between apologies and life saving and mid-battle confessions, Nomura is willing to tolerate his presence, especially if he helps her move around heavy exhibits. They’re both going to live for centuries, they have time to work things out.
Barbara is actually the official head of the Order of Janus now. She took over in the middle of a bad situation, and since she can successfully negotiate with Trollmarket and flat out boss around the Trollhunter, everyone agreed to keep her. Strickler does a lot of the day to day stuff though. Barbara still has a job, and is a very busy woman.
Their relationship is complicated, but definitely there, and Jim has silently resigned himself to a step-sibling in the next few years. He doesn’t count on the surprise half-sibling, but he loves them both.
There is a strict “no children in Trollmarket” rule, instituted by Barbara, for the sake of safety. That rule gets broken during the rare crisis, when danger threatens Arcadia Oaks and it’s best to have everyone close to the Trollhunter in a secure place. Faye Lake is born during at Trollmarket during once such incident. Little Enrique and toddler Strickler are enchanted by their visit, and spend most of their childhood trying to sneak back into the place they can still dimly remember.
Jim, Claire, and Toby grow up and “go to college” (ie: get a cave in Trollmarket together and take online classes) but they visit regularly and are the cool older siblings most kids dream of having.
