Are little girls supposed to grow up this fast?

Are little girls supposed to grow up this fast? Look at little Sophie starting to sit up! She is such a doll. She doesn't cry or whine--unless she's hungry. Or tired.

She is starting to sit up a little bit, and is having fun with the Bumbo.And like her brother, she is already an amazing Wii player!Erin never gets into the blog too much, but she loves Sophie, and Sophie loves her. Even though she is growing up so quickly, she still sleeps alot. She has actually slept all night a cou;ple of nights this past week. She sleeps like a little angle. Night night Sophie.
