Should I worry that I will not be a good father?

Well,its too early to think of this but I have a seriosu relationship with a girl,and we make our dreams you know,we even talking about if we get married and have kids and stuff,I love kids,but I can't handle one,what I mean?I don't know what to say or do with a kid for example when it fells or fight each other you know,so I worry,would I be a good father?or I will be one of those who drown themselves into their jobs just to avoid talk with their kids?
