Why do most of us want kids even though there are always risks?

Nothing is 100% safe even though medicine have advanced. We're still taking a risk in even carrying a baby.

Among the things that can go wrong:
- Miscarriages
- Complicated or high risk pregnancy
- Gestational diabetes
- Preeclampsia
- Stillborns
- Maternal death
- Hemorrhage, etc

My own sister had it super hard with her 1st child. Both her and the baby's life we're at risk. They're doing good now but she wanted to go through it all and was more worried about her baby being ok than her own life.

Shockingly, 6 years later... she was pregnant AGAIN. The 2nd time was normal. I didn't think she would go at it again. Wow

Seriously why do most of us want to go through that even with all the risks?

Then I hear of a couple women that underwent either a miscarriage or stillborn... they still go for it again.

Even many years ago (1800's or so) when it was more risky for us, we still continue having kids. Wow
