6 Months Old!! Brynn is a very smiley little girl. She is rolling all over the place, army crawling to get to Joshua's toys, and getting up on all fours to rock back and forth. At her 6 month appointment she weighed in at 18 lbs (83rd percentile) and measured 27 3/4 inches (93rd percentile). Oh, and I should also mention, she says "Mama". Nevermind that she was talking to her toy frog.
