Yep, I had prematrial sex. I also had enough birth control on me to make sure I never got pregnant ( I mean, I was on the pill, plus used a diaprahm) and I made sure that any man who remotely got next to me had on slip covers and I'm decidely prochoice so If I had gotten pregnant, I would have evaluated my situation and decided whether or not to keep said child. In college definitely NOT.
And yes, when my dh and I decided to have kids (5 years after we got married) it was because we were ready to and had our house and although we had no idea how much a kid would cost, we both had good paying jobs.
Then you are one of the few that has a triple redundant system. I am betting that 99% of people don't. And as you stated, and I agree that we need to stop sugar coating everything, including birth control. It fails, and a condom isn't the end all be all. For procreation or lack of it, and for STD's.
All of that being said, I cannot fathom how any mom would force her child into the streets. There is no excuse for that at the ripe old age of 15. And I stand by what I said that the mom who does that, shouldn't be a mom in the first place.
Make rules for your kid and your grandchild, she can finish school, get a job and support herself and the baby. And I don't buy the waking up everyone in the house, most memare quite capable of sleeping through anything as are the other teens or kids in the house. So what if you have to wake up the kid to make her feed that baby, I wake up several times a night, it is no big deal and it doesn't last long. These are all just excuses to not deal with a pregnant teen. Kicking her out to the street just makes problems for everyone, and really what "human" could actually do that to another one, especially a helpless baby. Their time will come, Karma is a *****.
