Screen time for toddlers: what the guidance says, and what actually works
The published numbers are easy to find and hard to live by. Here is what the main guidelines actually say, why the number is the least useful part of them, and the difference between a timer that governs one app and one that governs the device.
What the published guidance says
Two bodies are usually quoted. They broadly agree, and both are talking about entertainment screen use, not video calls with a grandparent.
Under 18 months
The American Academy of Pediatrics suggests avoiding screen media other than video chatting. Video calls are treated differently because they are a conversation, with a real person responding in real time.
18 to 24 months
If you choose to introduce screens, the advice is to pick high-quality material and to watch it together rather than handing the device over. At this age the adult beside the child is doing most of the teaching.
Two to five years
The AAP suggests limiting non-educational screen use to about one hour a day on weekdays. The World Health Organization’s guidance for this age is no more than one hour of sedentary screen time, and states plainly that less is better.
This is a summary of public guidance, not medical advice, and no guideline can account for a particular child, a long flight or a week of illness. Your paediatrician or health visitor knows your family; a web page does not.
Why the number is the least useful part
Almost every parent has met the gap between the hour on the page and the hour in the house. Four things matter more than the total, and all four are within reach on a bad afternoon in a way that a clean number is not.
- What it replaces. Twenty minutes instead of a nap, a meal or going outside is a different twenty minutes from the one that buys you a shower.
- Whether anyone is alongside. A toddler watching with an adult who names things and asks questions is having a conversation. The same minutes alone are much closer to nothing.
- What is on the screen. Something slow and quiet that the child can control asks a great deal less of a small brain than something fast that plays on regardless.
- How it ends. A session that ends with a warning and a predictable stop teaches something. One that ends with a device being taken away teaches something else, and you will pay for it tomorrow.
Two kinds of limit, and only one of them is enforcement
This distinction is worth being clear about, because app marketing tends to blur it — including, if we are not careful, ours.
Device-level limits
Screen Time on an iPhone or iPad, and Family Link or Digital Wellbeing on Android, cover the whole device. They can cap total use, set downtime, restrict which apps open and require a passcode a child does not know. This is the only kind that actually enforces anything, and it is built into the device you already own.
Apple Screen Time →In-app timers
A timer inside one app can only stop that one app. It cannot see what else the device is doing, and nothing prevents a child from closing it and opening something else. It is a useful piece of self-discipline for a household, and a genuinely good thing to have in a toddler app, but calling it parental control would be overstating it.
What Kidster’s limit is, and is not
Kidster has a daily limit of 15, 30 or 60 minutes, or none, set in a Parent Zone behind a small arithmetic problem. You choose the hour it resets, so it can roll over at bedtime rather than at midnight. When the time is used up the app stops and asks for a grown-up; you can then add 15 minutes, 30, an hour, or unlock the rest of the day. Time spent behind the parent gate does not count against the allowance.
The part that belongs in plain sight
That limit governs Kidster and nothing else. It does not monitor the device, does not report on what your child did, does not block other apps, and cannot stop a child closing Kidster and opening something noisier. If what you need is a limit across everything, set it in Screen Time or Family Link. Ours is a sensible default for one app, not a substitute for that.
Ending a session without a fight
Warn once, in a unit a toddler understands. “Two more animals” lands where “five more minutes” does not, because two is a thing they can count and five minutes is not.
Let the app be the one that says no. A timer that stops on its own is a rule; a parent reaching for the tablet is an opponent. This is most of what an in-app limit is actually good for.
Keep the stop in the same place every day. The reset hour matters less than its being the same hour, because the predictability is what removes the negotiation.
Have the next thing ready before you stop, not after. The gap between screen and nothing is where the meltdown lives.
A toddler app that stops on its own
Free to download, with no account and no adverts. Set the limit and the reset hour in the Parent Zone, and the app will keep to it without you having to be the one who ends it.
