16 weeks development

We had a quick little doctor’s appointment yesterday, monkey, and everything seems to be right on track. Your heart rate was hovering in the 140s (I already knew this since I check in on you at least twice a day haha) and all is well. I’m not really sure what the point of the appointment was, other than to get my blood drawn for the second trimester portion of your prenatal screening. We should know the results of that blood test in about two weeks. Other than that, it’s just business as usual I suppose. I mentioned to the NP that I was experiencing sciatica, and as I suspected…not a whole lot that can be done. Joy. 🙂

Let’s talk about the changes and development you’ve gone through this week:

Apparently gender dependent developmental differences appear for the first time starting at 16 weeks. You’ll learn about this debate in biology class, little monkey, but there are a plethora of gender specific behavioral differences between males and females and it has long been debated whether this is a biological phenomenon or an environment (nature v. nurture)…eeeep I can’t wait to teach you all this stuff! 🙂 Right now, for instance, female fetuses exhibit mouth movement more frequently than males and this difference increases with advancing age. (<–biological evidence) 

In contrast to the withdrawal response seen earlier, stimulation near your mouth now evokes a turn toward the stimulus while you open your mouth.  This reflex mimics the rooting reflex which will persist after birth to help you find your food supply during breastfeeding haha.

This week your are able to make sideways movements with your eyes. Though your eyelids are still sealed for protection, the muscles which control your eyes are starting to work! I’ve read that you scrunch up your eyes when bright light shines through my abdominal wall and probably looks like a reddish glow to you! This is one of my favorite things to do right now…I sun my belly outside and imagine what you are seeing!

This week you have probably found your umbilical cord too and might be holding on to it. So cute! Don’t worry, your grip isn’t yet so tight it will restrict any blood flow.

Here are a few 16 week development pictures pulled from the internet!

My favorite…A model, to scale of what you look like inside me right now!

Mommy Em loves you monkey!


About Em

After the loss of our first pregnancy, we took a much needed vacation to Costa Rica to enjoy each other and clear our minds. Well, as luck would have it, we brought home much more than great memories and great tans...our own little Costa Rican souvenir. Here is our journey!

    Every time your mommy posts development pictures of you I can’t help it but think that in a few short months you will be here with all of us…. how exciting Baby Em. I know you are gorgeous already (after all I’m sure you will take after your grandma – Or grandmas if Grandma Minoletti has anything to say). But either way you will be gorgeous and healthy, just like your Mommy and Daddy when they were born. See you this week end.
