The Shocking Truth About Parents And Screen Time
Listen On
As a pediatric ophthalmologist and mom of three, I spend a lot of time thinking about what our kids are really seeing — and what we are showing them, even when we don't realize it.
Not just what's on the screen, but what our children observe when we are on the screen.
How much of your child's brain development is quietly being shaped by your micro-moments of distraction?
How often do we glance at our phones during what we think are ordinary, harmless moments — and what is that actually costing our kids?
If you've ever told yourself, "I was only on my phone for a second," this episode will change the way you think about that second.
In this episode of In Focus: Vision, Clarity and Eye Health for the Whole Family, I break down a landmark study just published in JAMA Pediatrics in May of 2025 — one of the largest of its kind — and share what the science now tells us about parental screen use, interrupted attention, and child development.
What makes this episode different is simple.
This isn't abstract research.
This is the data behind the moments that happen in every home, every day — and a practical system to help you protect what matters most without throwing your phone in the ocean.
Why This Topic Matters Right Now
We talk a lot about screen time for kids.
But this conversation is about something we talk about far less:
Screen time for parents.
A major meta-analysis by Toledo-Vargas and colleagues, just published in JAMA Pediatrics, analyzed 21 studies involving nearly 15,000 children across 10 countries. All of the children studied were under age five — the most critical window for brain development and neuroplasticity.
The researchers asked one central question: does parental technology use in the presence of a child affect their development?
The answer was a statistically significant yes.
And as both a physician and a parent, that reality is impossible to ignore.
The Word You Need to Know: Technoference
There's a new term for that micro-moment when your watch buzzes during tummy time, or your phone lights up while you're reading a bedtime story.
It's called technoference — and the JAMA Pediatrics study has now quantified exactly what it does to your child's developing brain.
The research found negative associations across six key developmental domains:
Poor cognition — thinking skills, language processing, problem solving
Reduced pro-social behavior — empathy, sharing, kindness toward others
Lower attachment — the secure bond that forms the foundation of your child's confidence
Increased internalizing problems — anxiety, sadness, and withdrawal
Increased externalizing problems — tantrums, aggression, acting out
Greater child screen time — because children mirror what they see us do
Small effect sizes, yes. But in public health, small effects compounded across an entire generation produce massive societal impact. Think second-hand smoke. Think lead exposure. It isn't a sledgehammer. It is a slow drip.
The Finding That Changed Everything
Here is the part of the study that truly stopped me in my tracks.
The researchers compared two types of technoference:
Distraction — actively engaging with your device while your child is present. Scrolling Instagram during breastfeeding. Checking email during floor play. Mentally checked out for extended periods.
Interruption — being present with your child, then getting pulled away for just a few seconds by a notification before returning.
We used to assume interruption was better. Shorter. Less harmful. You came right back.
The study found no moderating effect.
They are equally harmful to developmental outcomes.
Why? Because of what happens neurologically in that gap.
The Science of the Interrupted Parent
In pediatrics, we talk about serve-and-return. It's the back-and-forth exchange between parent and child that literally builds the architecture of the developing brain. The baby coos. You smile back. The toddler points at a truck. You say, "Yes! A red truck!" Each exchange lays down neural pathways.
When your phone pings and your eyes leave your child — even for a second — you miss the return. The ball drops.
We know from the famous Still Face Experiment that when a parent's face goes blank or shifts to a screen, it triggers a cortisol spike in the child. They look to you and ask, in the only way they know how: Am I safe? Am I seen?
When that signal goes flat repeatedly, children ramp up their behavior to pull you back.
The tantrum is not bad behavior.
The tantrum is a bid for connection.
The Strongest Correlation in the Entire Study
Of everything the researchers measured, the single strongest association was this:
Parents who use screens around their children have children who use more screens.
It is the ultimate monkey-see, monkey-do.
We cannot ask our children to put down their devices when we cannot put down our own.
The study also highlighted maternal mental health as a significant factor — and the cycle it can create. Stress leads to phone use. Phone use creates disconnection. Disconnection triggers acting out. Acting out increases stress. And the loop continues.
The good news? We can break it.
A Three-Step Protocol for Reducing Technoference
You don't need a complicated list of rules. You need a system you can actually use — one that works whether your child is two or sixteen.
Here is my practical framework, based directly on the JAMA findings:
Strategy 1: The Eye Level Rule
If you are on their level — on the rug, in the bed reading a story, at the dinner table — the phone is off limits. Not in your pocket. Not face-down beside you. Physically not there. If you need to check it, stand up and walk to a designated "standing zone" like the kitchen counter. This adds friction, and friction breaks the habit loop.
Strategy 2: The Phone Foyer
When you walk in the door, dock the phone. Put it in a basket, on a high shelf, plugged into a charger in another room. Out of pocket means out of reach. You will hear the ringer if it's an emergency. You will not see every ping and preview that pulls you away before you've even registered it.
Strategy 3: Narrate the Tool
When you genuinely need to use your phone — to check a schedule, set a timer, text your partner — say it out loud. "I'm picking up my phone to check the weather. Now I'm putting it down." It turns the device back into a tool. It models intentional digital use for your children. And it keeps you honest, because narrating mindless scrolling out loud is nearly impossible.
A Note on Guilt
Before I wrap up, I want to say this clearly:
This is a no-shame zone.
Fifteen years ago, I had HGTV on in the background during tummy time. I told myself it was fine because my baby wasn't facing the screen. I was doing QuickBooks during breastfeeding. I thought being physically present was enough.
We didn't have this science then.
We do now.
Guilt is not a strategy. Knowledge is a strategy.
Final Thoughts
This study isn't here to make you feel like a bad parent.
It's here to give you information that empowers you to be a more intentional one.
Your eyes are the most powerful parenting tool you have — more than any toy, any class, any app. When you lock eyes with your child, you are downloading confidence directly into their developing brain. You are telling them: You matter. I see you.
Don't let a notification sever that connection.
The email will be there in ten minutes.
This moment will not.
