Raising your sisters or brothers it waaay different. Yeah my two older sisters raised me, with their kids, one at which had her first kid at 16, and my other sister had her first at 21, I was barley 18. I moved out of my house when I was 15 to live with my sisters, because my mother and I didnt get along. It was hard then, I had to get a job, go to school then go home to a house with my sisters and a baby. And at night you wake up to crying at all hours of the night. Dont get me wrong, you will want a baby one day, I didnt plan on gettin preg, when I did, and I wouldnt give my baby girl up for anything in the world. Sorry if I sound like im being mean, but here it is, having and being around babies is hard, sometimes fun, most of the time tiring. You have to have money all the time, diapers, food, fourlma, clothes, Dr. Appt's. And you have to have money for your self too. Dont just take it from me, having a baby at a younge age is hard.
