OK….here we go!
First and foremost……Babies are NOT as expensive as we are led to believe!
Diapers and formula, are pretty much all that are going to be out of pocket expenses.
State and Federal aid are availible and reasonably accessable. They should cover all prenatal, birth, post, and infant care.
As for Dad, that is up to you, time, and circumstance. Follow your head and then your heart. Becoming a mother will blow your mind wide open in regards to what is best for (your) children.
It will all be alright. Do what you KNOW is right, and nothing else will fail.
