Fred,
No one can ever explain to someone what having a baby can do to you. Now that you have one, you will notice a softer spot in your heart for all children. You will love that child more than you could have ever before imagined or understood. You will not feel this same feeling for other's children, but will have a new respect and ability to see their children through their eyes. It is nearly impossible to put clearly into words. I have two children of my own, still young... 3 & 5. I am very excited for you and what your future will hold with your new one. Congratulations! Just wait and see.
Cheers,
Fangar
