I'm 20 and all I can think about is having a baby.
Is there a reason you're thinking about having a baby?
I think I would be a good parent.
It's normal to want children, but you should be ready first. You're young, you've got plenty of time to settle down and have a family after you're finished with school and have a job. You want to be prepared for having a child, right?
So you are saying I will become a bad parent.
Absolutely not, I'm sure you'll be a fine parent. All I'm saying is that you should be ready first. After all, it's expensive to raise a child, so you should make sure you're financially secure and ready to be a parent first.
