When to give your child their first phone.

The most common age children in the EU and US receive their first smartphone is now 10 or 11 (Common Sense Media, 2024 Census). The most common age researchers in the field of adolescent mental health recommend giving a smartphone is 14 or later (Haidt, The Anxious Generation, 2024).

The gap between those two numbers is the entire reason this question is hard.

The two-part question

A useful way to break the question apart:

1. Does the child need a way to communicate with the family when they're not together?
2. Does the child need to be in the social-media / variable-reward feed economy?

The answer to (1) is often "yes" by 10 or 11, especially if the child is starting to walk to school alone or visit friends without an adult. The answer to (2), on the data we have, is not "yes" until 14-16, and arguably later.

The mistake is to treat these as the same answer.

A staged approach that survives peer pressure

Stage 1 — Basic phone (calls + texts only), age 10-12. A "dumb phone" or a feature phone with calls and SMS only. No social apps. Reliable for safety. Most children handle this better than parents expect.

Stage 2 — Family-shared smartphone, age 12-13. A real smartphone, but it lives at home except when the kid is going somewhere. A specific list of allowed apps; no social apps; supervised setup. WhatsApp with family only.

Stage 3 — Personal smartphone, age 14+. Their own. Still no social apps until 16 if you can hold it. Devices out of the bedroom at night, always — see the sleep rule for why this is the most important rule in the entire setup.

How to handle the "but everyone has one" line

Acknowledge it. Don't dismiss it. The phrasing that works:

"Yes, almost everyone in your class has one. We're going to be a year behind, on purpose. Here's why, and here's what we'll do instead."

Then, the "instead" matters. A child who can't have the smartphone but can roam to the park alone, can walk to school by themselves, and can have a friend over without a check-in is not, in any meaningful sense, behind.

What the research actually says

The most-cited synthesis on this is the Twenge & Campbell 2018 paper in Preventive Medicine Reports, which found a dose-response relationship between adolescent smartphone use and lower wellbeing. The effect was strongest in girls and was strongest for social-media use specifically. Calls and texts produced no detectable harm. This is consistent with the mechanism that makes feed-style apps differentially harmful.

Translated into a rule: phone is fine, the variable-reward feed bundled with it is not.

When to revisit

Every six months, sit with your kid at the kitchen table and have a five-minute conversation about whether the current rule is working. Be willing to be wrong. Be willing to give them more rope earlier than you planned. Be willing to take it back if a problem shows up.

The rule is not the point. The relationship around the rule is.
