Wise Beyond Their Years/Playing With

Basic Trope: A child shows a level of maturity significantly beyond that expected of their age group.
 * Straight: Alice is able to manage a shop for a while while her father is out buying groceries/saving the world, and keep her younger siblings in line, despite being only thirteen. And she still completes her homework on time and gets good grades.
 * Exaggerated: Alice owns her own shop, complete with license, is raising three brothers, and regularly defeats evil all on her own, despite being only ten. Oh, and she manages to keep up at school despite all this.
 * Justified: Alice's parents are away often and there is no one available to babysit her or her siblings. In extreme cases, Alice suffered from Parental Abandonment or even Promotion to Parent, possibly while fleeing from aforementioned parents.
 * Inverted: Alice is a Man Child.
 * Subverted: Alice looks competent at first, but we see her quickly abandon her adult duties to play with siblings.
 * Double Subverted: Alice appears to be abandoning her post in the shop to play with her friends, but as soon as the kids are out of sight they start planning how to stop the Diabolical Mastermind from taking over the city.
 * Parodied: The Diabolical Mastermind is regularly defeated by a five year old with a yoyo Once Per Episode, while the "cunning" Ragtag Bunch of Misfits who are supposedly the heroes fail miserably due to being Adult Children.
 * Deconstructed: A fourteen year old Alice is forced to take on a job and keep a household due to one of her parents being insane and the other missing, and the state she lives in having no child support services. For a while she manages to balance her job, chores, her own and her siblings education and care for her parent, possibly while avoiding myriad dangers, but the pressure ultimately gets to her and she suffers a breakdown, becoming violent and turning to drink.
 * Alternately, Alice's maturity causes her to be a Fish Out of Water with everyone; her maturity causes her to have significant problems relating to and making friends with her peers, and people who are more in line with her maturity (I.E. adults) refuse to take her seriously because she's so young.
 * Alternately again, Alice shows extremely Troubling Unchildlike Behaviour due to her excessive understanding of how the world works and all the necessary evils society needs in order to operate. This can range from apathy towards mass murder all the way to being able to commit murder with a good justification.
 * Alternately yet again, Alice damn well knows she's wise beyond her years and isn't afraid to flaunt that at every opportunity, which eventually causes her to develop a massive superiority complex.
 * Still alternatively, Alice owes her unusual maturity to unpleasant circumstances that required her to assume an adult outlook on life long before she was ready. As such, her unnatural loss of childhood manifests in severe mental and emotional problems after she reaches physical maturity. Symptoms can range from abnormal sexual development, damaged emotions, or even full-blown regression into the childhood she'd previously lost.
 * Reconstructed: Alice is forced into the above situation, but just before Alice snaps completely the family starts to get helped by the community, her siblings start chipping in and eventually some sort of equilibrium is formed where Alice is still dealing with adult responsibilities, but has enough support from friends and family to avoid being unable to deal with them. The fact she's growing up is helping as what was nearly impossible at fourteen is a merely very hard and stressful at fifteen.
 * As she is shunned by her peers for being more mature than them, she finds friends in older people, who accept her intelligence.
 * Zig Zagged: Alice is shown running her own buisiness in one scene, playing with balloons in another, managing a household in another, and then laughing at cartoons the next scene along.
 * Averted: Alice is just a normal ten year old. She goes to school, laughs at cartoons, gets defensive when she's called Just a Kid, and enjoys being with her friends.
 * Enforced: This shows aimed at kids, we want a Kid Hero who can handle adult problems. The kids will love her and she'll be a good role model, which will shut the Moral Guardians up for five seconds.
 * Lampshaded: "You know, most little girls wait until they're at least eighteen before they start talking to dragons."
 * Invoked: Alice's parents force her into adult-like situations and problems, in hopes that she'll mature faster.
 * Defied: Alice is quick to palm off any arduous responsibilities onto hapless adults whenever the threat of having to handle a serious responsibility rears its ugly head.
 * Discussed: "Ah, great. You're one of those kids who raise the adults, aren't you?
 * Conversed: "You know, from watching this show you'd think that adulthood begins at ten."
 * Played For Laughs: Alice is by far the youngest of the Ragtag Bunch of Misfits yet while they're all running away from the yeti, she's the one who calmly recognises that its a statue.
 * Played For Drama: Alice is left to look after her siblings and her insane remaining parent, and is forced to handle things that would be strenuous even for adults.
