My brother and his wife have been married for over 11 years and were thinking they might not be able to, but he just called me and she’s 12 weeks along. I can’t wait to be a bad influence. 
Congratulations!
Buy the kid a drum kit and a puppy.
Being an uncle is so much fun! Especially the being a bad influence bit.
Uncledom is the best! You get to take the little one out, spoil said little one rotten, and then when the little one gets sick/cranky you give the kid back to the parents and say, “I think sump’ns wrong, fix it!” 
Oh boy! You get to teach someone armpit farts!
Yeah, that really is the core of the whole being an uncle experience i’ve found. It’s pretty great.
Well that and the armpit farts. 
Yep. Can’t wait.
Aww, congrats to the whole family. How exciting for you all!
