Congrats man!!,It'll be fun.I have 2 boys,one is 6 and the other is 2...I was 23 when my first son was born,it's a new scene but for the most part it's not as bad as some people think.It's a lot of fun.
There are trying times, to be sure, but for the most part...it's a hoot! You have the opportunity to create a legacy that will, for better or worse, long out live you. Make the most of it.
Congratulations!
