Measurements and weight estimation

We officially have an on-time, 3 lb 15 ounce (estimated weight) little man stretching and jumping around in my belly.

His measurements were great at todays ultrasound.  I am 31 weeks, 1 day along. For those of you who are geeks like me here are the official measurements:

BPD: Biparietal diameter (BPD): The transverse width of the head at it's widest.

8.09 cm which is the average size of a 32 week, 3 day fetus.

HC: Head circumference

27.52 cm which is the average size of a 30 week, 1 day fetus

AC: Abdominal circumference

27.42 cm which is the average size of a 31 week, 3 day fetus

FL: Femur Length

6.18 cm which is the average size of a 32 week, 0 day fetus

The weight estimation came out to be 3 lbs, 15 ounces which is 1798 grams. Wow!

To put that into comparison, Bree was estimated at 500 grams at birth and about 1 pound. After being given fluids and meds she was finally stable enough to be officially weighed in at 1 lb, 5 ounces. So Derrick is almost 4 times the size that Bree was.

Derrick should gain about a half a pound a week until he is born. So if I am 31 weeks right now we'll just say he's four pounds. That leaves us week 32, 33, 34, 35 and 36 to gain weight. (We're hoping to do c section at the end of week 36). That will estimate his birth weight at around 6.5 pounds! How awesome will that be???!!

I am so proud that he is doing so well and is growing right on schedule. I am so blessed.

You and Derrick are doing great. Hope you can go the the appointed 36 weeks. Does your uterus look OK in the ultrasounds? Sure hope so. Love you all
