This is a portrait of how Finn is wired, drawn from the birth chart. It is not parenting advice, not a diagnosis, and not a substitute for professional support. If something here worries you, talk to someone who knows your child in person.
Talk and quick handling of whatever is in front of him come naturally to Finn, and behind that lightness sits a much more serious sense of purpose. The Sun in Capricorn keeps a long aim in view, even when the manner around it stays curious and mobile. What grows is someone who sounds casual about things he has every intention of finishing.

Finn lives at the front edge of his own energy, wanting a thing and going after it in the same breath. Fire gives the heat and cardinal gives the push, so the day arrives in bursts of starting rather than long even stretches. Interest runs hot while it lasts, and once a plan exists in his head, waiting for it feels like being held still.

Warmth directed straight at him is what brings Finn back after a day that has taken too much. The Moon in Leo needs the upset to be seen and taken seriously by someone who matters. Being laughed at while raw, or having the feeling treated as a small thing, turns a passing low into a long one. Attention given generously ends it sooner than any reasoning will.
Certain objects become part of Finn's sense of safety and cannot be quietly removed. Cancer on the second house ties keeping to feeling secure, so what he holds onto is chosen by comfort rather than worth. He hoards small things, remembers where they came from, and notices immediately when one has gone missing from the set.
Under an audience Finn tends to step slightly sideways from whatever everyone expects. Attention registers as pressure to conform, and the response is a small deliberate difference in what he says or how he stands. The Midheaven in Aquarius makes being typical feel worse than being odd. Approval matters less than keeping some visible proof that he has his own mind about the thing.
Care keeps pulling Finn back towards the smaller, nearer world of people he already knows. The North Node in Cancer shows as a lean towards tending rather than achieving, towards being known at home rather than admired further out. His competence is real and comes easily, yet the moments that settle him are the ones where feeling gets named and somebody stays close.
Asked how something works, Finn lays it out in order and leaves nothing important unsaid. Mercury in an earth sign shows in the steadiness of his explaining, the pause before answering, the preference for the useful word over the impressive one. He would rather be accurate than quick, and he dislikes being hurried through the part that matters.
Words come out of Finn after he has already decided they are worth saying, which makes speech slower and firmer than it looks from outside. Mercury in Capricorn tends toward short, weighted sentences with little decoration. He dislikes being caught in a statement he cannot stand behind, so silence often stands in for a half-formed answer, and certainty arrives late but arrives solid.
Finn holds steady in a group while the noise sorts itself out around him, and other children drift toward him once the game needs someone to hold the shape of it. With the Sun in an earth sign, his weight in a room comes from staying put and finishing what he started. He takes a while to warm to new company, then works alongside them easily.
Pushing for something, Finn argues the whole shape of it out loud, often widening the question rather than narrowing it. Mars in Sagittarius moves by conviction, so wanting a thing and believing it is fair arrive together and sound the same. He pursues hard while the case still feels alive, then drifts once the matter is agreed and the next question has already caught him.
Information settles slowly in Finn, tested against what he already knows before any of it is accepted. Mercury in Capricorn takes things in with a kind of caution that can look like slowness and is closer to thoroughness. He wants to know whether a thing holds up, who says so, and what it is for. Once learned, it stays learned, and he rarely needs telling twice.
Among other children Finn takes on the organising without being asked to, working out who is doing what and how the game actually runs. He tends toward the older end of a group, steady rather than loud, and other children lean on that steadiness. Capricorn in his chart shows in this preference for order over noise. Silliness that goes nowhere loses him quickly.
Finn holds on to things that have been his for a long time, well past their use. Old items keep their standing simply because they were there first, and replacing them is treated as a real loss. He gathers and stores, tucking belongings into places he considers safe. Habits form around the familiar, and what is worn or outgrown is still counted as his own.
Finn holds the shape of his own day close and dislikes having it handled by other people. Scorpio on the sixth house cusp gives meals, rest and small tasks a private weight, so a change in routine registers more than it looks like it should. Tiredness and hunger tend to stay hidden until they are considerable, and then they show in mood rather than in words.
Finn leaves people with an impression rather than a firm account of who he is. Different adults describe him differently, and each version sounds true. Pisces on the tenth house cusp keeps the public name soft at the edges, built on atmosphere and kindness more than on anything countable. His reputation shifts a little with the company he is in.

A large share of Finn's chart collects in Capricorn, so one note sounds through most of what he does. Weight in one place gives a child unusual steadiness there and less flexibility elsewhere. He tends to meet very different situations with the same approach, which works well often enough that he rarely looks for another one.
Undercurrents get noticed by Finn long before anyone names them, and the noticing rarely becomes a comment. Mercury in the eighth house draws the mind toward what is hidden, unsaid or only half explained. The question worth holding is how much he has already worked out that he has decided to keep to himself.
