First of all, no its not too young, just realize you have to put your kid first in EVERYTHING you do from this day forth til you die. Not like on some marriage shyt where til death do us part is just words, but forever ever. Raising a child is serious business. That doesn't mean you can't have fun, get drunk/ high, twerk at the club anymore, but you definitely must incorporate moderation of the aforementioned in your life.
Anyway, congratulations, and kelp your circle of people surrounding you positive, so that you can in turn soak in and put out positivity, because your kid will soak up whatever kind of vibe you put out.
