I'm pretty young to be saying this and i no that so DON'T JUDGE ME!! (I'm 18)

For some time now I've been thinking about having a family of my own but I've run into many problems which smacks me back into reality. Yes I want a baby, I have 3 older sisters and a younger brother with children that I have raised up until this point in my and there life's (ages 1 month-7 years old). This should be the prime reason for me NOT to want children but it's just made me want 1 even more. I feel that I am fit enough to be a parent, I have a well paying job, I'm out of school #ClassOf2016 🙌, and I no what to and not to do when it comes to taking care of myself and others. I have a pretty BIGG family so adding an additional baby would make it a bit harder for out living arrangements.

What should I do to KICK this #BabyFeaver
