re: I just found out I have 3 year old son

Just love him and spend as much time as you can with him. Tell him every chance you get that you love him. I can't help with the getting to know him part. But I have 3 boys 5/4/1 and the main thing they need is love and support and discipline but ease into that, has to be hard on the kid finding out who he thought was his dad isn't.

If you do it right your relationship will have no lasting consequences and he prolly won't even remember he thought somebody else was his dad.

Like I said love him and let him know that verbally and through your actions. Show him attention but don't let him be a brat. You can explain things when he is older, just be there for him.

And congrats and dude thanks for stepping up and doing the right thing. You are in for a bumpy but very rewarding ride.
