Pregnant at a young age

The other day my girlfriends, me and my daughter went to the mall to just walk around. As my friends entered a store without me cause my daughter ran off and I went to chase her. A vendor stops my daughter and I to show me some curlers. He probably didn’t mean anything when he asked me about my daughter and i about our age. Mind you, I had my first daughter at 18, and then my daughter just a couple months ago. He said to me “isn’t having a baby at 18 a little too young?” To me personally, I don’t think that’s too young. It’s young, yes but not too young. At that age we should be mature enough to know our responsibilities and the consequences when having sex. I just felt judged because I had a baby before the “right” time. Is there ever truly a right age to have a baby? People still give birth at the age of 40 & that’s perfectly alright. But at 18? Everyone makes a big deal. Maybe it’s just me. I don’t think people have the right to judge someone if they decide to have a baby at that age. I love my baby girls and I wouldn’t change anything.
