Should I Get a Car Mirror to Monitor My Baby?

Q&A on car safety

Emily Oster

2 min Read

Hi Emily (big fan)! My question involves infant car safety, specifically the baby car mirrors used to monitor your child in their car seat. I know there is a risk that these mirrors can become projectiles in the event of an accident. I also know there is a risk of infant asphyxiation on long car rides, especially before your baby has head and neck control. Is there data to understand which risk is greater?

—Back Seat Blues

Conceptually, I love this question because it grapples very directly with the idea that no option is completely safe, an insight I’ve written about before. The sales pitch for these mirrors is that they enhance safety by allowing you to check on your child. But wait! They might become a dangerous projectile! It’s easy to go from here down a road of safety obsessiveness. Maybe you get a padded mirror. Or you surround the baby with more padding. But wait! That’s a suffocation risk! Maybe the whole car could be somehow padded?

I’m kidding, but only just. Once we start down the safety road, we can go anywhere, as in this amazing music video. In this particular case, both of the risks are really, really small. With a correct-size car seat and insert, infant asphyxiation in the car is extremely rare. Similarly, the confluence of circumstances in which there is a bad enough accident to dislodge the mirror at a high enough speed to damage you and in which the accident itself isn’t the problem … this is also extremely unlikely.

What I think is notable is that, in this case, the focus on the weighing of these two very small risks actually may lead us to ignore the much larger risk: a car accident. Cars are dangerous, and you have to pay attention. Focusing on paying attention to a baby in a mirror is a risk for distracted driving. And that is a real risk. It’s the possible increased risk of an accident in the first place that is the problem, not the mirror projectile.

In conclusion: do not get a mirror, but not for the reason you said.

Reflux: It’s more common than you think! Comment “Link” for an article by @thepediatricianmom breaking down the information we have about reflux — what it is, what you can do, and red flags to look out for.

This graph shows how reflux changes with age. Nearly half of all babies experience reflux by 3 months, often peaking around 4 months before improving by their first birthday. And remember, if you’re struggling, you’re not alone. The most effective treatment for infant reflux is time. It will get better!

We’re heading into a three-day weekend, which means a lot of you might take the opportunity to do some potty training. 

Here are some things to keep in mind:
🚽 It takes longer than three days (based on the data!)
🚽 Your child will have trouble staying dry at night.
🚽 Poop sometimes comes later than pee – this is common, you just have to work through it.

Trampoline parks: great way to get the sillies out or injury haven? Or both? Comment “Link” for an article breaking down a 2023 study on injury trends in trampoline parks.

Here’s a visualisation based on the paper, showing the injury rate by area. Beware the foam pit and the high-performance areas! Slam-dunking, though, seems fine.

Screens have become a ubiquitous part of classroom life. Is this a good thing? Today on the ParentData podcast, I talk with @jessgrosewrites from the @nytimes. She recently ran a survey asking about kids’ screen usage after not being able to find studies and data on the subject.

“Nothing is all bad or all good. But I think overall, there just has been very little scrutiny into something that has been a massive shift in the way kids learn in the past, let’s say, two decades.”

How do we get our kids excited about math? Can every kid be a “math kid”? Shalinee Sharma of @zearnmath shares her insights on the ParentData podcast. 

When I offered her a magic wand to fix math education, she told me: “We have to pair understanding with memorizing. And the best way to understand really anything, but especially math, is simple pictures, concrete context, just make it feel real, not abstract and theoretical. What’s a negative number? Think about if sea level is zero and then you dive into the ocean, that’s a negative number. And then you climb a mountain, well that’s a positive number… We just need pictures to be a part of mathematics.”

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.
