Evidence-informed, without overpromising

Why play matters for children: what research says.

Play is part of how children explore, move, communicate, and spend time with people who care for them. Here is a short guide to credible pediatric and early-childhood sources, and to what they do—and do not—tell us about an activity app.

The practical takeaway is modest: adults can make room for play, respond to children’s cues, and choose activities that suit the child and context. Play does not need to be expensive, elaborate, or adult-directed to be worthwhile.

What the evidence says

1. Play is linked with a range of developmental skills

The American Academy of Pediatrics clinical report The Power of Play reviews research on developmentally appropriate play with parents and peers. It describes play as an opportunity to support social-emotional, cognitive, language, and self-regulation skills, and to strengthen caregiver relationships. The report was reaffirmed by the AAP in January 2025.

2. Responsive back-and-forth interaction matters

Harvard’s Center on the Developing Child describes “serve and return” as the back-and-forth exchange between a young child and a responsive adult—for example, when a child gestures or babbles and the adult responds. The center explains how these interactions support early communication and social skills. Play can be one natural setting for that exchange; the idea is to notice and respond, not to deliver a lesson.

3. Movement can be part of everyday play

CDC guidance says children ages 3–5 should be physically active throughout the day and encourages caregivers to support movement during play. For ages 6–17, the CDC recommends 60 minutes or more of moderate-to-vigorous activity daily, with aerobic and muscle-strengthening activity. These population guidelines do not replace individual medical advice or account for every child’s circumstances.

4. Good early learning respects the child and context

NAEYC’s developmentally appropriate practice framework describes strengths-based, play-based learning that attends to children’s individual differences, families, and communities. That is a professional framework—not a fixed recipe. Educators use their knowledge of each child and setting when deciding what to offer.

How an activity finder can help

Knowing that play matters does not always answer the immediate question: “What can we do right now?” The upcoming Moments app is intended to make that search easier. Its planned library of 1,200 activity ideas can be filtered by age (under 1 through 16, including multiple ages), inside or outside, and 2, 5, 10, or 20+ minutes. Activity cards are planned to show simple steps and supplies when needed, with favorites and optional reminders.

That is a convenience claim, not a clinical claim. These planned features are described for context; the sources above did not test Moments. We do not claim that using the app causes developmental gains, improves academic performance, or replaces responsive caregiving, free play, professional childcare planning, or medical advice.

Use activity ideas thoughtfully

  • Let the child’s interest and cues shape the activity.
  • Adapt movement, materials, sound, and duration to their abilities and preferences.
  • Leave time for child-led play alongside adult-guided activities.
  • For infants and toddlers, use safe, age-appropriate materials and close supervision.
  • For group settings, follow program policies and each child’s care plan.
