Messages rarely need minute limits. What needs a frame is the notifications: a bedtime for the groups matters more than any stopwatch.

The most important things to know

WhatsApp is the simplest app in this guide: messages, groups and calls, with no ads and no feed chasing your child's time. What needs a watchful eye isn't the app but the groups inside it.

The class group is the schoolyard after hours. Everything written there is read by everyone, can be saved by everyone and tends to carry on late into the evening. It's where both the good and the bad happen.

The default settings are worth going through: anyone with the number can message your child, and the group settings decide who can add your child without asking first.

What's positive about WhatsApp for your child?

As a first messaging app, WhatsApp is among the safest picks. Your child is in the room where the plans get made, in the class, on the team and in the family, with no algorithm, no likes and no ads in the conversations.

How can WhatsApp affect your child negatively?

The volume. The bar is so low that hundreds of messages in an evening is completely normal, and notifications with no bedtime eat into both sleep and concentration.

The groups. Being shut out of the class group is real exclusion, and screenshots from in there have a way of living on. Rarely the app's fault, but the app is where it happens.

And WhatsApp is no longer just messages: the Updates tab has channels and statuses, which is to say content to get stuck in. No algorithmic feed, but worth writing into the agreement.

Glossary

group
A chat with several people, up to 1,024 of them. The class group is the big one, and whatever is written there is read and saved by everyone in it.
admin
Whoever created the group, plus anyone they promote. Admins can add and remove people and decide who else gets to write, so the role carries some weight among kids.
status
Photos, videos or text visible to contacts for 24 hours, WhatsApp's version of a story. It lives in the Updates tab alongside the channels.
channel
A one-way feed from a celebrity, club or brand, in the Updates tab. Followers read, nobody replies, and this is the closest WhatsApp comes to content to scroll.
blue ticks
Two blue ticks mean the message has been read. Among friends that becomes a question: why read and not answer? The ticks can be turned off.
last seen
The line under a name showing when someone was last in the app. Kids read it closely, and it can be limited to contacts or hidden.
voice note
Hold the microphone and talk instead of typing. Many teenagers send dozens a day, and a group can turn into a pile of them to listen to.
disappearing messages
A setting per chat that deletes messages after 24 hours, a week or 90 days. Screenshots still work, so a message can live on after it has gone from the chat.
mute
Silencing a group for eight hours, a week or for good, while staying in it. Your child stays in the group and stops hearing it, which is often the gentlest fix.
