What do you consider a young mom?

Br

I had my son at 18, and obviously it’s young to have a baby. But when I told someone I was “super young” when I had him, they told me that 14-15 would be super young. But 18 isn’t that bad. I was kind shocked when she said it cuz most people I tell are like astonished it seems like. My sons grandma acted like she’d never heard of a teen mom before I got pregnant. So idk, is 18 shockingly young to have a baby to you?
