Why are so many teens so confident about ttc?

I'm shocked at how many teens are TTC on this app. I've seen post from girls 16 years old convinced they'll make great mothers. How?! Who is encouraging this?! I'm 18 and trying to pay off college why the hell do you want to purposefully put yourself in the position where you're changing a diaper everyday when you just learned to clean your own butt?!!

I can't take care of myself at 18 much less another human being.

I'm not talking about the moms who had babies when they were young, I'm talking about teens right now TTC.

So many naive teens on here make me ashamed of my generation.

What do you guys think? Why are so many teens TTC? Let me know what you think.
