Why does the chance of getting adopted is more if your younger?

They are liable to kill you, since you're not their real folks.

the younger you get them, the more you get to mould them to your idea of what children should be. Once they get to teenage years, you're more or less taking on someone else's ideas & faults, taught to the teenager (plus, teenagers up for adoption have often been through a number of families & tend to be less socialised & more problematic - on average, I must stress).

They're more expensive in the fact that they'll eat all the food and drive the power and water bills up substantially. However, I think they're adopted less because they aren't cute little kids, and that tends to be what adopting parents are looking for

Maybe your friend said it in a jokingly fashion, as teenagers are often jokingly referred to as 'trouble'. To answer your question: I think most people who adopt a child want to do it early on, so that they can have the full experience of having a child, from birth onwards.

Most want a baby or someone younger because they may not have the chance to have children biologically and they want to watch that child grow up. They want to be the person that has raised that child from a very young age up until they are adults. They want the complete experience.

I think it might have something to do with adopting someone who's less developed and thus more impressionable/influencable. More of an imprint on raising them- at least theoretically- since they're younger.

Because people want to raise the child the majority of its life, like a real parent, I suppose.

Teens are almost adults most people want to adopt children or babies idk

Teens are more difficult 2 deal with

No one wants a stranger in their home... they want a kid they can bring up in their own way. Make into family.
