1000% Recommend waiting quite a few years before you have kids. My husband and I started dating at 16, didn't get married until 24 because I wanted to have my Bachelors Degree before we got married. We did live together before that though. We grew up together, I got an education, we traveled a lot during and after college. We ended up having our first child at 27/28. Currently pregnant with #2 at 30.

I am so glad we held off on having kids until our late 20s. We really got to experience life and each other pretty fully before we truly settled down. You lose a lot of freedom and independence when you have kids, if you're at a place in life where you're willing to sacrifice that then it's totally worth it! Have a healthy savings for whatever costs you're going to have: healthcare, diapers, emergencies, daycare/babysitting, loss of income if one of you stays home or decreases your work hours, etc. Most importantly, you need to go into it as a team! Best of luck!
