As all kids, I started my musical career with the flute, but google translates the kind of flute I'm talking about into a recorder? Is that what you are talking about? What a weird name for it. Anyway, I was pretty good in it tbh.
Most people only know the soprano recorder, because that's what you learn as a kid.
But there are many different kinds.
From top to bottom: bass, tenor, alto, soprano and sopranino.
The alto was my instrument, but I also played the tenor or the sopranino sometimes.
Anyway, after a while, I was done. I wanted to play drums. So I got my first set when I was about 14 and have played for years. Got lessons, got a couple of diplomas, played in a band for like two years (we were bad...). I loved it. I have bought my own gorgeous set but now I live so small I don't even have the space to store it...
I like to try some other instruments some day. I know I have a feel for it. I understand melody and rhythm. I can read sheet music. I don't like to LEARN though. I want to just be able to play it. Which is why I loved the drums, I swam through that for years until it got harder and I stopped practicing.
I long to play again. Any sort of instrument. Someday.
Oh and why all the recorders for kids? Because it's a cheap and simple instrument that fits kiddos hands and doesn't generally take a lot of technique to learn to play it. It teaches kids the basics of music: melody, rhythm, reading sheet music, etc. If you can't play the soprano recorder, you probably just don't have that music gene.
Also if your kid want to play the saxophone for example but is still changing teeth or is wearing braces, than you might have a problem. So for many people the recorder is seen as a first introduction into playing music as it's cheap, fits a kid, and relatively easy to learn. And after that first year or two, they decide on what instrument they really want to play.
Also I need to make a note about the reason why so many feel negative about recorders. 1: you HAD to learn it when you were a kid and you didn't want to. 2: most kids suck at playing it and can't produce clean, clear notes. Therefor it sounds horrible. But believe me, if the player know what (s)he's doing, it sounds pretty nice! Of course music is all about preference, so you might not like the sound of it anyway, (just like I don't like violins, ugh), but let's not blame the instrument.
