I don't ever plan on having a baby. Just watching Secret Life of the American Teenager has made me skeptical, even though it's just a soap opera teen drama show. I was watching it the other day, and I said to my sister as Amy was crying in pain, "Why would anyone willingly go through that?" I suppose the end result of having a child to take care of would justify it for most people, but I really couldn't care less.
I'd rather adopt. Seeing and reading so many stories of little kids and teens living on the streets with prostitution and everything these days has made me want to adopt and give them a temporary home, someone they can trust, before sending them out, now financially and physically and mentally stable enough to make it on their own.
I think short-term foster care would be amazing.
On-topic, having the baby at a young age comes with risks. However, as one person wrote, in old times (i.e. the Bible if you believe in it), having babies with kids as young as thirteen was acceptable and even encouraged. Twelve year olds did it too. As long as the body is capable of reproducing, physically it is fine.
But the school thing, also. You shouldn't have a baby until you're out of school and (possibly) have a job. Marriage would be good too. But hey, if you're ready to drop out of school and marry and have a baby at 16, I'm not going to say any different. Probably not the best choice you could make, but it's at least something.
Eighteen, Tsukasa-sama, seems like a perfectly good age to have a baby.
Congratulations, by the way. I'm curious as to know the name too X3
