Only god can judge. That goes for all the people that keep judging teenage pregnancies.
Yeah some teenagers can be irresponsible and immature but they are not all like that. Anything can happen in this world of ours and in your perfect little life.
You might have it all one day and not have anything the next, so don't judge b/c you never know what is going to happen.
Some might not have all the material things to offer their child but if they can love their child, care for and nurture their child than that will be enough to have a child who knows right from wrong.
If you raise your child right and pay them some attetion then they are not going to seek love from somewhere else. Like drugs, or be 12 years old trying to have a baby. Those kids that are trying to have kids just need some attention and love from their parents.
I say this b/c I know women who had their children while being a teenager and work their ass off to provide for their child and have done the right thing, and I admire that kind of commitment and strenght. Not everyone has that but some do.
