I could tell the boys were growing again, so I weighed and measured'em...
B1: 4'9" and 80 lbs.
B2: 3'10.5" and 44 lbs.
Both boys have grown a quarter inch in the last two months, and both of them have grown 4.5 inches in the past 2 years!! Amazing! B1 is definitely going to be taller than me, at the rate he's going. I mean, I was 5'3" in 7th grade, and I grew to be 6'3" by my senior year -- B1 is already 4'9" in 4th grade!
