Congrats.
I have one point of advice; get ready to pay out big time, but remember child support always costs more.
You need to change diapers with a smile, and pretend this intrusive creature doesn't make you feel a crazy rage now and then.
Congrats and good luck, there is no more important thing you will do in your life so don't blow it. You have to develop a relationship with your child, it isn't a given thing. Talk to he/her. Make faces, do belly farts and walk them around the house with them clinging onto your fingers until they are spent.
It's simply awesome.
There is no greater love you will ever know than that of your child. You have never experienced unconditional love. Get ready for it, it is a life changing experience.
