I was 26 and 29 when my first two children were born, and nearly 44 when the "second generation" child came into the world, so I approached this late-comer with some previous experience. But I don't know that I was any more set in my ways at 44 than I was at 26, and I don't know that I had any less energy. Fatherhood requires work, and it will change your life, but it is worth it.
I gagged the first time I changed a diaper. Thousands of diapers later, I was prepared for all manner of other horrific childhood emissions and, you know what -- I took care of them without flinching. Parental instinct kicks in somewhere along the way, and you just know what to do.
I've found that being a father again at a later age truly keeps me young. I am fortunate to remember what it was like to be a child, so that helps me to relate. And I've found that there are some universal experiences and episodes of childhood -- things that happen, questions that are asked. And I keep getting the great priviledge of playing again and experiencing the world anew through my children's eyes.
Of all the things that have happened in my life, being a father is the best, hands down.
Congratulations and enjoy!

LOL My husband never overcame that! He can't scoop a catbox either!! But he had the wonderful talent of getting the kids all cuddled up next to him, he'd softly hum and off to sleepytown they went!
