My daughter is now 14 months, and was born at 4 lbs 13 oz.  When we brought her home in the car seat, she was tiny.  I thought she'd never outgrow it since there was so much room to grow!  Well, the other day as I was putting her in the SUV, I realize that she's grown so much that her legs can no longer be outstretched in the car seat and her feet are on the back seat even with her knees bent.  It just brought back memories of how much she's grown so far, and how proud I am of this little kid.  Now for some shopping for new toddler car seats... :)
