Growing to be big men one day

After losing some weight after birth, both boys are growing again. Weighing in Friday at Dr. Neel's office, Davey's weight was up to 6 lbs 4 oz and he's grown 3/4 inches longer. Benji's weight was up to 5 lbs 4 oz, just under his birth weight, and he too has grown about an inch.
It's likely these will be very tall men. Sandy at 5'9" has two taller sisters, Kristin 5'10" and Susan at 6' tall. Dave is 6'1" and his brother Steve is 6' 6". All Dave's male cousins are taller than he is. Both grandfathers are 6' 2" and both grandmothers are 5' 8" tall. It's safe to say the odds are good that neither boy will ever be jockey material.
