I'm an Uncle twice over as of early Saturday morning!
My brother and his wife just had their second baby girl, Katie Elizabeth, as of around 2:00 a.m. Saturday morning. She weighed in at 8 lbs. 9 oz., was 21" long, and was surprisingly not as wrinkled as her sister was when she was born.
My wife and I went by the hospital to meet our new niece yesterday morning. Baby and mom and both doing very well. Makayla, the older sister, seemed very excited to have a little sister (once she figured out what the new one was).
Of course, now that my brother and his wife are just getting past the diaper stage with their first, they have to do it all over again with their second. I'm sure that doesn't matter though. They are both beyond happy.
