Our New Baby This Week


40 Weeks


It's hard to say for sure how big our baby will be, but the average newborn weighs in at a little over 7 pounds and is about 20 inches long. I’m guessing he’s going to be 9 lbs 12 oz and about 23 inches.  Anybody else care to guess?  Email us!  Our baby will continue to grow with every passing day (his nails and hair will continue to get longer, too). Our baby's skull bones are still separated and they'll stay that way to allow the bones to compress enough to fit through the birth canal during labor (you'll notice soft spots or "fontanels" on our baby's head for a year or more after birth).


Despite medical advances, there's still no way to know for sure when a woman will go into labor. I may not be as late as I think, especially if our baby wasn't conceived exactly when we thought (this happens more frequently when your due date is based only on the date of your last menstrual period and you haven't had an ultrasound in the first half of your pregnancy). But even with reliable dating, some women still have prolonged pregnancies, and experts don't really understand why.
I still have a couple of weeks before I'll be considered "post-term." But to be sure our baby is still thriving, this week — or by the start of 41 weeks at the latest — our practitioner will want to begin special testing to monitor our baby.

A biophysical profile (BPP) consists of a detailed ultrasound to look at our baby's overall movements, breathing, and muscle tone (whether he opens and closes his hand or extends and then flexes his limbs), and the amount of amniotic fluid that surrounds him (important because it's a reflection of how well the placenta is supporting the baby). It may also include 20 minutes or more of heart rate monitoring. Alternatively, I may have what's sometimes called a modified BPP, which includes monitoring our baby's heart rate with a fetal monitor, and an ultrasound evaluation of the amount of amniotic fluid. These tests are usually done twice a week.

This is what the baby looks like now:

I found this picture of the synechea and thought you might like to see it:



At the doctor’s appointment this week:


I am measuring 41 weeks.*

I am fully effaced and dilated 2 cm.**

The baby’s head is not engaged.


*Coincidently, the measurement from the top of your pelvic bone to the top of your fundus is roughly equivalent to your baby’s gestational age.

**In labor, a woman’s cervix must efface/soften/ripen and then dilate to 10 centimeters before she can push a baby out.  Active labor is considered 4 cm on.



Here’re some pictures of the nursery:

We’ve had some inquiries about a baby registry.  We are registered at Babies “R” Us.



Note that, for the purposes of this chart, babies are measured from the crown (or top) of the head to the rump (or bottom) until about 20 weeks. After that, they're measured from head to toe.
