Help?!?

I’m 18 and I’m desperate for a baby, I’m in a committed long term relationship, we’re financially stable and we both have very loving and caring families. Since I live in England, iv already gone to college and left with the highest marks which could send me to uni one day if I want. Me and my boyfriend (he’s 21) both really want the same things and we’re saving for our flat.

Iv been around babies my entire life, and feel like I was born to be a mother. Am I the only person who is young and wants a baby?
