In PMs it was suggested that if Yui decides to become a true psychiatrist (rather than an immensely empathetic person who just so happens to have an internalize diagnostic suite) some of the problems she might be dealing with in Fae children are things like :
'Gaiaphobia' i.e. fear of touching the ground.
If they're flying to some degree by around 5 to 10 (presumably with some variance in milestones by individual) then that's right in time for the earliest ages most phobias develop (not a solid area, but there is some evidence that animal phobias and such tend to develop before five, while the rest tend to come in after ten) and it's not hard to see how a Faerie child might get scared of the ground. Especially if they distinguished between safe grounds (floors for instance) and unsafe ones (natural terrain perhaps) and might therefore be mistaken for agoraphobia at first.
So a parent thinks their kid has social issues but really they're scared of dirt.
Extreme sensory sensitivity : i.e. intolernace to hot, cold, or light
I suppose the racial senses and minor inclinations would tend these towards being racially grouped. Not as a certainty but at the level where proper statistical analysis would show a significant relationship. Though the greater senses of Faeries in general are far more likely to play a bigger part. Obviously we don't really have much real life data to go on for this sort of thing but it would follow that increased senses = denser and larger sensory processing areas of the brain = more capacity for things to go wrong there.
Could also link to cases of puberty hitting too fast. Their Faerie bodies gain sensory acuity too rapidly in the process and they're left struggling to process the data properly. In fact it occurs that later study would likely formalise a lot of those cases of maladaptive puberty into a core problem of uneven development due to some areas outpacing others.
Huh, I guess in a way this means that the lesser shadow of 'Out of Time' cases is something that will continue to follow them throughout their life as a species. Might even be that the propensity for it is increased due to the exact mechanisms that the Transition used to ensure that those like Rika would still be able to develop most of their brain function (read: growing up and maturing into adults) at a normal rate.
Specialized childhood development care among Cait Syth and Sidhe children : I imagine Cait Syth become fully ambulatory younger than any other Fae phenotype, but they're typically slow to reach other milestones. They'll typically be the last to start speaking for instance as their brains prioritize motor control and sensory processing and then catch up elesewhere later.
Meanwhile Sylph children hit flight milestones earlier?
Oh wait, misread that. Well the notion might stand but Sidhe children are an interesting topic. Gonna be hard work for pyshcologists among the Fae to get Sidhe to trust them enough to help with this sort of thing. Especially Sinnoach Sidhe if past mentions of them and their kids are coming back to me correctly.
Different priorities make sense as a lore remnant of the whole bestial origins. And would certainly make for kitten like kids. Though it'll probably also scare the hell out of some of the early parents when all the milestones are different (a problem for all Fae parents that one) and so they are left with no idea if their child is developing at a healthy rate or not. Cait parents in particular are going to have a time between codification of milestones across Fae as a whole and the realisation that Cait are just naturally different in the early development stages.
Mediating between first generation parents and their second generation children. A huge one no doubt as parents have to cope with raising children for whom all of this is . . . normal.
Managing and prescribing things like puberty blockers for precocious Fae youths when their bodies adaptation drive kicks in during puberty. i.e. It is not natural (or healthy in either the physical or emotional sense) for your little girl to go from playing with her cute child dumbells while dad gets in his workout to wanting to spot for dad as he bench presses in less than a year.
They could possibly develop this particular medicine fairly early (yay alchemy skill!) with some input from Pixie healers as it could be a similar mechanism of action to what they use to slow Blossomings, especially if different gardens use different blends of certain plants due to regional variance in what is easy to find. Use alchemy and magic to supplement efforts at isolating and extracting commonalities amongst them and boom, you can scale up to have a Faerie version. It becoming a priority to develop after some early freakouts with Arrun Home residents would make sense and then you have a perfect set-up for first generation parents demanding this treatment (at just about the right time in the future for Yui to be grown up and getting into her field) when it's not necessary at all. They're just scared and worried and mournful over what feels like missed years because they haven't internalised that their children are developing differently but are very much still developing.
Like I imagine that Fae whose development jumps ahead mostly just end up spending more time as teenagers. The age of becoming an adult being far less variable then the age of puberty.
Edit : Fae typically 'pop' their wings around a year old at which point they can instinctively slow a fall to be survivable from most heights.
They also typically develop their instincts to orient themselves three dimensionally from the ages of 1-3 over which time their flight ability expands to wing assisted hops.
By five, a Faerie can fly short distances at moderate speeds. And by ten they're reaching the 'athleticism' age where things like training their stamina and coordination really start to come into their own.
Wing pop age is going to be a godsend for parents. Combined with some increase in durability even with an untrained baby body and mortality from accidents is certain to be a bit lower. Though the first parent to discover this when they drop their baby while flying and their frantic dive overshoots the little gliding giggling child...well they are going to be pretty fucking scared by the experience. On the other hand this probably means Faerie kids are more inclined to fall off things intentionally as they grow up.
Developing flight and gliding instincts as it might be, this sort of behaviour is sure to scare the hell out of first gen parents.
This would predate a lot of the more abstract spatial awareness that develops by about nine or ten, which makes sense given the increased capacity for three dimensional orientation that Fae must possess. A comparison would probably find that the order of some of those abstract measures is altered given that Faerie kids have a different priority set. Also little toddlers hopping around with their wings makes for an adorable image indeed.
So it lags behind walking at first, but not by that much. This would suggest that Faerie back rides are going to be very popular with young Fae (and possibly aid their development of spatial reasoning) who are probably horribly jealous of their older siblings and such for being able to fly. Who can fly the longest is definitely replacing who can run the furthest for such kids. Also they're going to be getting plenty of grinding of their toughness and battle healing stats what with all the aerial tag they'll be playing. Here's hoping second generation Fae are better at automatically gliding even when knocked out
Thanks for giving me a reason to go digging through z-library Trigger. Been a while since I did much reading on developmental psychology.
