Congradulations!!
I've been an uncle for 11.5mths now and I must admit the first month was great, then he learnt how to cry haha and it was hell for the next 6mths and the past month or 2 has been fantastic.
I'm teaching him to walk, he's starting to talk (baby jibberish, nothing english). I've taught him to wave, walk, use a phone and tv/hifi remotes, open and shut cupboards and he loves spinning around on chairs etc.
I'm yet to buy him anything because the first purchase i'm gonna make is a little HRT race suit but they are still too big for him
