Who switched my babies?

Something mysterious has happened in the past week or so. My babies have switched personalities. Either that, or someone came in the middle of the night and switched them.

Gracie, the smaller of the Twinsies, has been, since birth, the more anxious of the two babies. She screams like a banshee and goes from quiet and happy to inconsolable in less than a second. Luke was my laid back baby. Gracie could scream and scream and scream and Luke would continue sleeping like nothing was happening. His cries were half hearted at most.

This past week, Gracie has really changed. Not only is she growing like crazy, but her movements have smoothed out and she takes longer to agitate. Her big eyes are staying a dark blue-gray and her eyelashes are so long! She no longer looks like a preemie, instead, she is starting to look like a baby. Even her preemie clothes are starting to be snug! Don't get me wrong. She can still scream louder than the engine of an F18 fighter jet, but it takes longer for her to get upset and she responds more quickly to the sound of Ed's voice or mine.

Luke's face has thinned out and he is the smiler. Even in the NICU, he was the laid back one. When Gracie got a reputation for being "feisty" (read high maintenance), Luke was the baby the nurses enjoyed working with. Recently, he has started to be easily agitated and needs to be held constantly. His cries are heartbreaking! He often cries so hard that he makes himself throw up. He is guaranteed to get the hiccups from crying as hard as he does.

I'm just trying to figure out what happened. Who switched my babies? And who do I have to talk to in order to get them switched back?

Seriously, it is so much fun watching them change. The bonus, of course, is that all this change presents a challenge for Mommy and Daddy. We love challenges. Especially ones as cute as these!
