When my mother was pregnant with my youngest sibling, her pregnancy was risky and her doctor brought up the idea of abortion. I remember the day very clearly, she and dad came home, and called me and my little brother and told us about it. We were kids ourselves, 6 and 8 y/o but we understood and we said it's okay, no more baby is alright. And dad was supportive as well. But mom was the only one who was clinging to her child. And decided to take the risk anyway. Fast forward to now, and I can't imagine a world without my sister. She's a sweet girl and a happy person. Just think, her entire existence would've been erased in a moment if no one had fought for her.
Not saying I'm 100% against abortion, there are cases which are understandable, like a risky pregnancy, or a child conceived from rape, or a heavy medical condition detected before birth...etc.
But I'm saying that often times, the decision making is harder than what actually follows. You make mountains out of molehills, thinking that you aren't ready to be a parent, and sometimes that may be true, but other times, it's just how every future parent feels (I did) and it's okay, you'll be fine. You'll adjust and learn.
