I absolutely hate kids and I don't want to have a child ever in my life.
Why do you feel this way about children?
They are loud and annoying
Some people are not cut out to be parents. You don't have to be one. Instead, you can take care of animals.
I can't have a baby because I don't want one.
It's perfectly fine to choose to be childless. It's far better to know you don't want children and not have them than it is to have children and regret it.
