I want a baby!!

Okay so im only 17 and I know! Im way too young to be wanting a baby but ever since I was like 4 i've had baby dolls, I would carry my pets around like babies, fed them with bottles, etc. I am obsessed with babies. Im going to school for b-1 education and I want a baby so bad right now, but the idea of getting pregnant at 17 scares the absolute shit out of me. I've thought about what it would be like to have a kid now and it just sounds so perfect and my boyfriend wants one too. We both agreed to wait at least 3 more years  (willing wer still together) for when we have a house and are financially stable. But im going crazy I want a baby so bad. I babysit infants all the time and they're just so perfect! Im baby obsessed•_•
