Well, why don't you ask the kids who are the offspring of those teens? I think they have good answers. I totally agree that seventeen year old parents are not experienced enough to have a baby. Maybe a few.
It has always been this way. Maybe not in all states but for just twenty years ago if someone had a baby at 17-19 that wasn't a big deal because one was an adult by then at these times. My parents were barely eighteen and nineteen when they had me, and it was not a scandal.
for sixty years ago dying at forty wasn't a big deal either, but I disagree that it's right to think that way, as with teenage pregnancies. It's not a human right to have a kid the same way as dental care and fresh water.
Teenagers who are 15, 16 and 17, as well as 18-25 doesn't think about consequences. To have a baby that young is to take a short cut thrugh life - a baby is a two-decade long project! and it can't be paused like a tamagotchi. the teen years should only be about the teenager and not a baby.
teenagers doesn't understand the burden, because having babies isn't supposd to be work or a burden. But it is like that for people who still have fights with their younger sisters about "where the heck my new shirt is". It's unnatural in our modern world.
Teens who wants a baby, think about: Risks. Having a baby in young age is a health endangering risk. Think about all the things you miss. Think about school. With a kid on your arm, will you finish school, get a graduate and a job to secure enough money to ensure a good life? What if not. You'll be alone, the kid will be alone, or sent to a foster home. imagine what that must be like for both of you. Not all foster homes are good.
Think about tomorrow. Tomorrow is a day where thoughts and POV's are reborn, somehow. Is it right tomorrow? I don't think so. A baby is not a pet, you can't give it back to the AS if you can't handle it. A baby is not a junior you, or your property, it's a person. An entire person. My parents didn't understand that and by god, i'll never do that mistake myself.
