Episode notes
Parents' Screens Reduce Toddler Language
- Parents' own screen use reduces toddler language exposure and vocalisations.
- A Kids Research Institute study using wristbands found toddlers heard fewer adult words when screens were present at home, costing thousands of word-exposures daily.
Screens Exploit Our Brain's Ease Bias
- Brain circuitry favors low-effort dopamine hits from endless novelty on devices.
- Becky Kennedy frames this as biology not morality, explaining why children gravitate to effortless entertainment on phones and tablets.
Put Devices Out Of Sight To Change Habits
- Remove visible devices and set predictable no-screen windows to change habits.
- Becky Kennedy recommends moving phones out of rooms and picking one short daily window to practice, then ask children to gently remind you.
