#1276 - Mum’s Screen Time: What It’s Really Doing to Your Child’s Development

Dr Justin Coulson's Happy Families

Are your phone habits impacting your child’s growth?
We all know kids and screens don’t mix well—but what about parents and screens? A compelling new study has uncovered a strong link between a mother’s screen time and her child’s developmental outcomes. In this Doctor’s Desk episode, Dr Justin and Kylie Coulson unpack the latest research on "technoference" and what happens to our children when our eyes are glued to our devices. The results may just change the way you use your phone—especially around your kids.

KEY POINTS:

• Study Summary: Japanese research of ~4,000 mother-child pairs found that more than one hour of screen use by mums in front of their children correlates with lower language and social development.
• Two Hours or More: Greater than two hours was associated with lower global development outcomes.
• Technoference: The distraction of devices interrupts “serve and return” interactions—vital for healthy child development.
• Modelling Matters: Kids mimic their parents—mums who use screens more are more likely to have kids who use them too.
• TV vs. Devices: Passive screen time (TV) is less harmful than interactive, overstimulating device use—but still not ideal.
• Screen Time ≠ Quality Learning: Despite nostalgic memories of “learning” from Sesame Street, research shows TV is a poor teacher compared to real-world engagement.

QUOTE OF THE EPISODE:

"Screens are a hollow imitation of real life... real development happens in person-to-person, face-to-face interactions."

ACTION STEPS FOR PARENTS:

1. Be Present: Put down your phone when you're with your child—especially in those early years.
2. Set Boundaries: Limit both your own and your child’s screen time with simple routines (e.g., no phones at the table or during playtime).
3. Model Mindful Use: Show kids what healthy tech habits look like—because they’re watching.
4. Prioritise Engagement: Make time for face-to-face chats, shared play, and reading together—real-life interactions build real brains.

Use Screens Intentionally: If you need a break, opt for TV over devices, and choose age-appropriate, narrative-driven content.
