What should I do? I like this girl so much, but....?

I am dating this girl that I first met around 4 months ago, we started dating, and now she's my girlfriend. We have been together officially for about a month, and I like her SO much, she is like perfect for me. Ahh, she is so gorgeous. The problem is, is that she has a 8 month year old baby.I am only a freshman in college, and currently don't have a job. I feel like we are starting to get serious, but this is a huge step that my girlfriend has a kid. Is it not? I mean, she can afford the baby, but I would be around when the kid grows up and everything, I would be influential to that kid's life, and currently my life sucks, it would be a terrible reflection. My friends will think I'm totally stupid if I tell them my girlfriend has a baby, because I'm only 20 years old, I have no job, and I'm an undeclared major. My parents would not really approve of me having a girlfriend with a kid either. I seriously don't know what to do. I like her TONS it's crazy, but this dilemma with the baby, I'm scared of what to do, do I stay with her????? (I'm not shallow by the way that I'm rethinking the relationship because of a mistake she made once in her life, but I'm just worried).
