Genetics are a funny thing. When people say MetaBoy has my eyes, but otherwise looks just like his dad, I just say "hmmm," or some variation thereof. I have a hard time seeing any of my features on him, and can only see a small few similarities to MetaDaddy. To me, I always figured MetaBoy was his own person, so he doesn't look "just like" anyone.
Then MetaGirl comes along and throws that theory out the window. She looks just like her brother. Sure, there are a few small personality differences (e.g., she startles if you whisper, which is usually hilarious), but visually...wow. The view of her when she's nursing is that much more impressive to me. I keep having flashbacks to the early days of MetaBoy. So weird.
She's growing fast, too...just like her brother. Though, hopefully she won't grow at quite the same pace. She was born at 6.5 pounds, and was 7.8 pounds at her 2 week appointment. Relatively speaking, she's nipping at her brother's heels. He was born weighing 7.11 pounds at 41 weeks. She was born at 39 weeks, and 2 weeks later, she almost matched his birth weight. He then went on to gain 2 pounds by the time he was 2 weeks old. And he doubled his weight by 2 months.
To make a short story long, she's getting big fast. I hope she stays as wee as she is for a bit longer than MetaBoy did.
Oh, and breastfed babies can grow at impressive rates. Always nice to reiterate :-D
