Nothing wrong with being a young parent per se, but it's just that the likelihood of being a bad parent multiplies exponentially, I think. For whatever reason (financial difficulty, unstable relationship, lack of acknowledgement of the magnitude of looking after a human being until it's too late), young parents generally find it tougher and I think (personal opinion) that there's probably a greater likelihood of them being a bad parent (however you want to measure that).
As I said earlier, there's nothing wrong at all with being a young parent, so long as you're a good one. Congratulations on your child, and good luck for the future. I'm sure you're a great dad.
