Everyone is right...say goodbye to uninterrupted sleer :-D. But when your child looks you in the eye, you will experience something that makes it all worthwhile!
I feel that what I have learned in my "advanced" (grin) age has made me a better parent than I would have been when I was younger. You will do just fine.
Advice...get used to the fact that your baby will christen your clothing with regularity. Remember to make sure your wife knows how special she is too.
P.S. You CAN handle the dirty diapers (nappies) ;-)
ARRRGH...sleep not sleer...and I even previewed!!!
