Do I Really Need So Much Prenatal Testing?

Q&A on IVF and advanced maternal age

Nathan Fox

3 min Read

I’m 44 and expecting my first in late November, conceived through egg donation. I’m in excellent health. My health care team has told me that from 32 weeks onward, I should have nonstress tests twice a week, because of my age and IVF. Twice a week! I’ll be working until 36 weeks and am juggling a lot in my life already, and adding that many appointments during business hours is going to stress me the heck out. Can you speak to the actual risks and benefits involved here? And/or whether I could do it at home, maybe with help from a nurse friend? There are no issues with my specific pregnancy; this is just “standard of care” for folks in their 40s (and maybe also for IVF babies). Thank you!

—Stressed by Nonstress

First of all, good luck with the pregnancy and glad you are doing well thus far. Very exciting!

Your providers are recommending antenatal testing, which is basically a structured testing protocol to assess the health of the fetus, specifically related to the health of the placenta. Antenatal testing is recommended for many conditions, some related to the health of the mother and others specific to the pregnancy. For example, antenatal testing is usually recommended for twin pregnancies, hypertension, diabetes (pre-pregnancy and gestational), suspected fetal growth restriction, and any other situation in which there may be an increased risk of placental insufficiency or stillbirth. However, there is a lot of variability in this testing from center to center, mostly because it is difficult to prove that the testing does what it is intended to do — lower the rate of stillbirth and improve outcomes for babies, as well as which exact testing protocol is best. The variability includes the exact list of conditions/situations that warrant testing, the specific test chosen, the starting gestational age, and the frequency of testing. So, basically, everything!

In your specific situation, it is common to recommend testing for someone age 44 who conceived through IVF. Although you are doing great, you do have risks similar to someone with pre-existing hypertension or diabetes, so it makes sense to test. NSTs twice a week at 32 weeks is on the more aggressive side of the curve, but certainly not unusual. Ultimately, you are able to opt out of it, but I wouldn’t push back too hard — if your doctors are used to certain testing, it’s probably best to just do it. The same is true for remote monitoring — it is feasible, but I would only recommend it if your doctors already do it regularly with other patients. The more you take them out of their box, the more likely it is that something may get missed. You can have a conversation with them to see if they are comfortable with less frequent testing (once a week) or starting the testing a little later (34 or 36 weeks), but if they push back, I’d leave it be.

Milestones. We celebrate them in pregnancy, in parenting, and they’re a fun thing to celebrate at work too. Just a couple years ago I couldn’t have foreseen what this community would grow into. Today, there are over 400,000 of you here—asking questions, making others feel seen wherever they may be in their journey, and sharing information that supports data > panic. 

It has been a busy summer for the team at ParentData. I’d love to take a moment here to celebrate the 400k milestone. As I’ve said before, it’s more important than ever to put good data in the hands of parents. 

Share this post with a friend who could use a little more data, and a little less parenting overwhelm.

I spend a lot of time talking people down after they read the latest panic headline. In most cases, these articles create an unnecessary amount of stress around pregnancy and parenting. This is my pro tip for understanding whether the risk presented is something you should really be worrying about.

Dr. Gillian Goddard sums up what she learned from the Hot Flash  S e x  Survey! Here are some key data takeaways:

🌶️ Among respondents, the most common s e x u a l frequency was 1 to 2 times per month, followed closely by 1 to 2 times per week
🌶️ 37% have found their sweet spot and are happy with the frequency of s e x they are having
🌶️ About 64% of respondents were very or somewhat satisfied with the quality of the s e x they are having

Do any of these findings surprise you? Let us know in the comments!

Should your kid be in a car seat on the plane? The AAP recommends that you put kids under 40 pounds into a car seat on airplanes. However, airlines don’t require car seats.

Here’s what we know from a data standpoint:
✈️ The risk of injury to a child on a plane without a carseat is very small (about 1 in 250,000)
✈️ A JAMA Pediatrics paper estimates about 0.4 child air crash deaths per year might be prevented in the U.S. with car seats 
✈️ Cars are far more dangerous than airplanes! The same JAMA paper suggests that if 5% to 10% of families switched to driving, then we would expect more total deaths as a result of this policy. 

If you want to buy a seat for your lap infant, or bring a car seat for an older child, by all means do so! But the additional protection based on the numbers is extremely small.

SLEEP DATA 💤 PART 2: Let’s talk about naps. Comment “Link” for an article on what we learned about daytime sleep!

The first three months of life are a chaotic combination of irregular napping, many naps, and a few brave or lucky souls who appear to have already arrived at a two-to-three nap schedule. Over the next few months, the naps consolidate to three and then to two. By the 10-to-12-month period, a very large share of kids are napping a consistent two naps per day. Over the period between 12 and 18 months, this shifts toward one nap. And then sometime in the range of 3 to 5 years, naps are dropped. What I think is perhaps most useful about this graph is it gives a lot of color to the average napping ages that we often hear. 

Note: Survey data came from the ParentData audience and users of the Nanit sleep monitor system. Both audiences skew higher-education and higher-income than the average, and mostly have younger children. The final sample is 14,919 children. For more insights on our respondents, read the full article.

“Whilst googling things like ‘new dad sad’ and ‘why am I crying new dad,’ I came across an article written by a doctor who had trouble connecting with his second child. I read the symptoms and felt an odd sense of relief.” Today we’re bringing back an essay by Kevin Maguire of @newfatherhood about his experience with paternal postpartum depression. We need to demystify these issues in order to change things for the better. Comment “Link” for a DM to read his full essay.

SLEEP DATA 💤 We asked you all about your kids’ sleep—and got nearly 15,000 survey responses to better understand kids’ sleep patterns. Comment “Link” for an article that breaks down our findings!

This graph shows sleeping location by age. You’ll notice that for the first three months, most kids are in their own sleeping location in a parent’s room. Then, over the first year, this switches toward their own room. As kids age, sharing a room with a sibling becomes more common. 

Head to the newsletter for more and stay tuned for part two next week on naps! 🌙

Bug season is upon us. Besides annoyance, this can bring up safety concerns, particularly with ticks. They are carriers of diseases, most notably Lyme disease. So what’s the best course of action?

Prevention is key! I suggest:
⭐ Regular tick checks
⭐ Using bug sprays with DEET 
⭐ Wearing long sleeves and pants in the woods

Some parents worry about DEET, but repellants with up to 30% DEET are recommended by both the CDC and AAP. The data says you’re in the clear, so go for it. Enjoy your summer!
