You Say Norbert, I Say Norberta

So, lately I've been having some doubts about whether my guess at Norbert's gender has been correct. And my reasoning is unbelievably sound. Trust me--I referenced Harry Potter. In case you're out of the loop: Baby Norbert has received his nickname from the Harry Potter series, and is thus named after the baby dragon Hagrid tried to raise in his hut. BUT! I started re-reading the 7th book last night and came upon this 'lil passage that has since made me start to question my judgment:

"Bin meanin' ter write fer ages. How's Norbert doin'?"
"Norbert?" Charlie laughed. "The Norwegian Ridgeback? We call her Norberta now."
"Wha--Norbert's a girl?"
"Oh yeah," said Charlie
"How can you tell?" asked Hermione
"They're a lot more vicious."

ekk! That's enough to plant the seed of doubt into my goldfish-sized brain!

Now, I know for a fact that I've never actually felt any kind of mother's intuition...if such a thing even exists. And I've never understood women who know the exact date of conception and what gender their baby is before even a doctor can tell. Since, apparently, I'm not tuned into this sixth sense of baby wisdom, and Harry Potter has effectively knocked me off of my I-have-no-doubt-Norbert-is-a-boy kick, I think I'll now go for the scientific approach. I figure I've got roughly a 50/50 chance of getting it right, so from now on, I'll spend most of my time waffling evenly between the two--at least then I'm guaranteed to be 50% wrong instead of having a 50% chance of being 100% wrong. Thankyouverymuch, J.K Rowling!

Norberta is 7 weeks old and the size of a Blueberry!
