Best wishes to your family on the arrival of another nephew!
Just be happy with the nephews, even if there is never a niece. My daughter has all male cousins, and two sons. No little girls in our family but I love the boys. The only problem is, there is no one to pass down my classic Barbie collection to. :P
Congrats Uncle Vampy! Hopefully in the future you will get a niece. But be prepared the girls will melt you heart and suddenly Uncle Vampy finds himself becoming Uncle Softie hehehe.
