5 1/2 month appointment

We had Sabrina's 5 1/2 month check-up a couple of days ago.  She's now a whopping 18 lbs 11 oz and 27 1/2" long.  We're thinking she's going to average out a little at some point, but she just keeps growing and growing and growing!  This weekend, she finally started rolling from back to belly and is just starting to figure out that, if she rolls, she can move around!  We're now starting to think about baby proofing the house, as she's going to be getting into things in no time.
