congrats wooohooo!!
hope everything went well for you two (/three) today!
lots of good advice already given in this thread. i know some of this has been mentioned already, but whatever. here are my two cents....
don't be shocked if you don't instantly bond with your baby. i found with my daughter the two of us clicked right away but it took my wife and her quite a while to bond. when my son was born it was the complete opposite. he and my wife bonded right away and him and i took quite a while.
both of our kids were c-section. not sure if that's your situation but if it is, be prepared to do a TON of stuff for your wife.
hopefully you have a perfectly happy/healthy baby - we did not... both times. i think i'm lucky with my personality becuz i wasn't really phased too much when the docs went over what was wrong with our kids - my wife on the other hand was a basket case. me being stable and having a "it's fine, we'll get thru this" attitude was really helpful to her. i remember talking with one of the NICU nurses after my son was born and i straight up asked, 'how concerned should i be for my boy?' the nurse was great and said that they see issues like he had 'all the time' and he would be fine in time. his issues weren't the "norm" (that's why he was in the NICU) but they see stuff like it everyday and are trained/educated to deal with those issues.
hopefully you have a camera that can take some sweet pics. i've taken thousands of pics of my kids and it awesome to look back even now and see how much they've changed (my daughter turned 4 in march and my son is 2 in july).
there has been a bunch of discussion on breast feeding. i know for my wife it took forever for her milk to come in with our daughter. it started up a lot sooner with our son. with our daughter she was getting to the point that she wanted to give up trying, but when it finally it happened and she's so thankful.
babies LOVE routine. up at this time, feed at this time, play with this toy, nap at this time. we did our best to keep both kids on a routine and for the most part it worked well. one thing that we found though is our kids just don't need a lot of sleep (guess they got those genes from dad! ha!) we were lucky if our daughter gave my wife 2 naps during the day for 45 minutes each. then we talk to one of our neighbours and both their kids have a 2 hour nap in the morning AND afternoon.... seriously?? what is that like??
one thing my wife and i discussed a lot was 'how we wanted to parent' our kids. that way we were completely on the same page and our kids don't get mixed messages from us. they know that our yes is yes and our no is no. it can be tough at first (ok - really tough), but sticking with it will make things a lot easier in the long run.
one thing that we decided was that we really wanted to limit our kids' screen time. the only stuff my daughter saw on tv for the first 3 years of her life was hockey and some stampeders football. other than that the tv was off around her. as a result both our kids have a bunch (ok - a crap load) of toys.... but they are sooo happy playing with toys and going thru books. we've noticed their attention spans are considerably longer than other kids we know that regularly get plopped in front of a tv.
as your kids get older and learn how to speak they will totally rat you out if you do something. last week my daughter comes running up to me, "DAD!!! i've got a secret to tell you about mom!!! she has a lollypop in her car and i get it when we come home from piano lessons and when we get in the garage i get 5 more extra licks!!" ha! ha!
enjoy every minute of being a dad - it's freakin' awesome! i love it and wouldn't trade it for anything... although i do want to add that people told my wife and i on many occasions that "you won't even remember what life was life before kids"... i call bs on that!! ha! i remember what it was like having time to work on my truck, play hockey 3 nights/week, hang out with my buddies, never miss a flames game (and that usually involved getting together with friends), etc.
