**Two to five hours a day is more than I would recommend for a 3-year-old, even when the apps are educational.** A useful starting limit is **no more than about one hour daily**: the World Health Organization recommends this for sedentary screen time at ages 3–4, including computer games, without an exemption for educational content. This is a guideline, not a threshold at which harm suddenly starts. [WHO guidance](https://www.who.int/news/item/24-04-2019-to-grow-up-healthy-children-need-to-sit-less-and-play-more)

The fact that she still enjoys friends, outdoor play, blocks and books is reassuring. But “she still does other things” doesn’t tell you how much time the iPad takes away from them. The American Academy of Pediatrics’ preschool guidance emphasizes what media crowds out—conversation, movement, imaginative play and shared reading—and specifically advises against unrestricted access to a tablet.

I’d replace unlimited access with predictable, short sessions, working toward roughly an hour total. To judge how it’s going, watch for:

- **Displacement:** less conversation, physical play, time with friends or shared reading.
- **Sleep:** delayed bedtime or reduced sleep. Children this age generally need 10–13 hours per day, including naps. [WHO guidance](https://www.who.int/news/item/24-04-2019-to-grow-up-healthy-children-need-to-sit-less-and-play-more)
- **Dependence:** increasingly demanding the tablet or needing it whenever she’s bored or upset. Occasional disappointment when a session ends is different from a persistent pattern.

Make some sessions something you do together: talk about the story, count objects, then try a related activity away from the screen. The AAP encourages discussing media and connecting it to real-world activities.

She may be learning from the apps. That benefit can coexist with a need for limits; you don’t need to wait for an obvious problem before setting them.
