Yeah, stay away from those damn leashes. Its your kid, a human, not a dog.
And holy crap, monkeys everywhere! If you can, get that leaf overhang thing from IKEA to finish the deal with the crib. Besides that, pretty sweet room for the kid.
As a recommendation about alcohol... make it seem like not a mystical voodoo substance. Also when the kid turn 13, give the kid a sip. Red wine perhaps... chances are, there will be no violent reaction but there is a great chance of stomach ache. If that doesn't nicely warn a kid about excessive alcohol... I don't know what will. Well, anyways, you have plenty of years to decide what to do.
Best of luck dude. Be amazed when the kid finally crawls, walks and bite. Be astonished when he says his first word. Make sure its not "OH SHIT!"... that's my oldest younger brother's first words. Made me cut down on the cursing for a few years...
Now personally, I had enough siblings, cousins and family friends' babies to play around with over the years. I have dealt with kids of all temperaments but I still don't have the slightest clue on how to actually raise a kid. I can be a sibling and a friend but man, a parent... freaks me out to even think about it. Main reason is its your kid. Not someone else.
