Introduction

Did we just stumble on one of the most controversial subjects in parenthood? Screen time for toddlers is an important topic, but it is also one of the areas in paediatrics that has the most contradictory information. “How much is too much?” “Is educational content okay?” “Will screens harm my child’s brain?” These are important questions, especially for parents of toddlers.

Let's get one thing straight: in this article, I will not be answering directly. Rather, we will break down what the latest scientific research tells us, in simple terms, so you can make informed choices about screen use in your home that are right for your parenting.

Developmental needs of toddlers

1 to 3-year-old, or toddlers, are in a rapid stage of growth in terms of their neural network. Their brains are absorbing information like a sponge, and their nerve cells are forming connections at a rate that will never be matched again in their lifetime.^1,2 

Sounds serious, right? At this age, kids learn best through active play, exploration, human interaction, and using all their senses. These early experiences shape every aspect of their brains. From language skills to emotional regulation, motor coordination, and problem-solving abilities.^1-3

Screens with their attention-grabbing properties have the same effect on toddlers that a bright light does on flies. This can be used as a tool in certain situations, like entertainment, socialising, or to calm a child temporarily.

On the other hand, when unsupervised or excessive, it can displace the crucial developmental activities we discussed above, mainly because screens don't provide the back-and-forth interactions that little brains need.

Current guidelines

Given this is an important subject, there are clear recommendations from most health authorities, like the World Health Organisation (WHO), the National Health Service (NHS), and the American Academy of Paediatrics (AAP). We will delve into details regarding benefits and risks further along in the article, but as a general rule, the guidelines suggest the following:

• Under 18 months: Avoid screen time altogether, except for video chatting with family
• 18–24 months: If parents choose to introduce media, it should be high-quality programming, and adults should watch it with the child to help them understand what they’re seeing
• 2–5 years: Limit screen use to one hour per day of high-quality programming, again with co-viewing encouraged

How parents choose to utilise these guidelines is ultimately up to them. These exist to support the healthy development of attention span, language, social skills, and sleep, which are the major areas of development that can be disrupted by too much screen exposure. But, otherwise, there is no right or wrong answer here, just guides for healthy development. Because at the end of the day, each parent will do what's right for them.

Potential risks of excessive screen time

There are a handful of studies that can support why reinforcing these limits is important. One would think that with its importance, screen time for toddlers would be a big research area. While it is an important area, it is worth noting why it is so hard to design a study that would establish a clear-cut cause-and-effect. 

Creating a scientific study to assess the potential risks of excessive screen time in toddlers is inherently difficult due to several factors. Ethical concerns prevent researchers from deliberately exposing young children to high levels of screen time, which limits experimental control. 

Additionally, many confounding factors, such as parenting style, socioeconomic background, and pre-existing developmental traits, can influence both screen use and child outcomes, making it hard to isolate screen time as the sole variable. Accurate measurement is also a hurdle, as studies often rely on parent-reported data, which can be subjective or inconsistent. 

Finally, because developmental effects may only become apparent over time, researchers must conduct long-term studies with large and diverse groups, which can be both costly and logistically complex.

Despite the challenges, studies have been conducted to get answers in this area. A recent study (2025) found that excessive screen time is associated with developmental delays in preschoolers.¹ These include difficulties with language, attention, and social interactions. Children who spend more time in front of screens may struggle more academically later, especially with self-regulation and communication.

Another study showed that screen time is sometimes used as a coping mechanism by stressed parents, particularly for emotionally reactive children.³ Unfortunately, this strategy has the risk of backfiring. Rather than helping children learn to manage their feelings, it can make behavioural issues worse by reducing opportunities to develop self-soothing skills.

Studies have also linked physical health and screen time, showing that kids who watch a lot of screens are more likely to consume sugary snacks (often advertised on TV) and develop dental problems. Screens can also reduce physical activity, contributing to weaker motor skills and less time outdoors.

Possible benefits of limited and purposeful screen time

While it’s easy to focus only on the negatives, it’s important to recognise that not all screens are created equally, and not all screen time is bad.

High-quality, age-appropriate media, especially when co-viewed with a parent, can have educational value. Programs that encourage counting, storytelling, or exploring emotions can support early learning. Co-viewing is especially useful in these situations because it turns the sedentary “watching” into a “together activity” where the parents can narrate, explain, and highlight things on the screen to make it more interactive.⁶

Teaching through screens also has its benefits. While this topic could warrant an article of its own, in short, studies show that children can respond to learning from a screen in much the same way they do to learning from a blackboard. In these contexts, screens are not used as a source of entertainment and may have entirely different effects on a child's development.⁶

For families who live far apart, video chats with grandparents and other relatives can foster bonding and support language development. This proved especially useful during the COVID-19 lockdowns, not only for children but for adults as well. The same guidelines still apply; however, video chats should be used as a tool for social interaction, not as a convenient way to calm or distract children.

As we mentioned before, not all screens are created equally. The key is intentional use. If screen time is chosen carefully, timed appropriately, and discussed together, it can become a small, manageable part of a child’s environment without replacing real-world experiences. 

Tips on managing screen time wisely

Considering everything we discussed, the current guidelines start to make more sense. Just thinking about a few steps could mean a meaningful screen use for a toddler with less worry about their development. Because let's face it, screens are in our lives and they are not going anywhere. 

• Stick to the one-hour rule: For children aged 2 to 5, aim for no more than one hour a day of high-quality and possibly co-viewed programming
• Be present: Watch with your child so you can talk about what you see. Ask questions like “What do you think will happen next?” or “How is she feeling?”
• Avoid screens during meals and before bedtime: Screens before bed can interfere with sleep quality and routines. At the same time, screens during meals interfere with general healthy eating guidelines
• Balance with play and activity: At other times. Make sure your toddler has plenty of time for physical movement, outdoor play, social interaction, and creative activities
• Create a media plan: Decide ahead of time when and where screens are allowed. This helps avoid battles and gives structure to your day.
• Lead by example: As adults, we also struggle with screen time, and your child will notice if you're glued to your phone. Try to model healthy screen habits for the sake of the whole family
• Use tech tools wisely: Many devices now offer parental controls and timers. Use these to limit exposure and choose appropriate content
• Provide alternatives: Have books, puzzles, or building blocks easily accessible. Offer these when your child seems bored or cranky, instead of defaulting to a screen
• Talk about it: Use screen time as a conversation starter. Even toddlers can reflect on stories or characters with a little help from you

Summary

How screens affect toddlers is one of the most debated topics in child development. Unfortunately, there is no one-size-fits-all approach here, which is why this article tried to focus on the scientific basis (however challenging as discussed above) on the topic. Toddlers are in a critical phase of brain development, and while screens can be helpful tools in certain contexts, they can also disrupt important learning and emotional processes if overused or used without intention.

While there are potential risks in screen time, like language delays, behaviour challenges, and reduced physical activity, there are also possible benefits, such as educational value and social connection through video chats. This is why there are no hard rules in screen time compared to the rest of healthcare, rather some guidelines that could support healthy development. These guidelines need to be shaped for every family's individual needs, but if we have to summarise it in one sentence, it's not about banning screens, it's about using them thoughtfully, and always putting real-world connections first.
