Screens and kids under 5: what we actually know

If you are here, you probably already feel the tug: screens are everywhere, and you want to get this right without guilt. Here is the short version of the research, written parent to parent.

1. The big studies are mostly observational

The largest studies follow thousands of families over time. They consistently find that more screen time in toddlerhood goes with lower developmental scores later, like the 2,441-child Calgary cohort and the 7,097-child Japanese cohort. They can’t fully prove cause, but the pattern is consistent.

2. Background TV counts too

3. Our habits matter as much as theirs

4. Small swaps beat big rules

• One predictable screen-free time each day
• Audio stories and books in place of one show
• Simple, open-ended toys within reach
