Congrats! Is this your first?Oh no... Our third, plus two others from my wife's previous marriage, so five total. Luckily, the oldest is sixteen and has always been a huge help. I grew up in a house with four brothers/sisters, so this is just like old times.
Something to be said for big families. I grew up with just three brothers, my wife with six brothers. On my mom's side, some of my cousin's families had as many as eight (thirty six first cousins total on that side). Reunions are lots of fun.
When someone mis-pronounces my name or calls me by the wrong name I like to say, "That's OK, you can call me whatever you like - just don't call me late for dinner!"
Those who come from big families usually get a kick out of that.
