Screen Time: How Does It Affect Your Child's Development?

Screen time is defined as time spent on various electronic devices — computers, tablets, smartphones, or watching TV, video or hand-held computer games (HealthHub SG, 2022). While it is tempting for parents to reach for electronic devices to provide convenience and entertainment, excessive screen time can hinder crucial aspects of a child's development.

How screen time affects development

Language acquisition

Contrary to common belief, even educational content on screens can impede a child's language development. Face-to-face interactions are essential for honing language skills — active listening, speaking, and understanding. Setting limits on screen time encourages real-life interactions, which can reduce the chance of language delays. Delays in understanding language might look like difficulty following conversation, expressing thoughts, or answering questions; missing words or using the wrong ones; relying on gestures; difficulty putting words into sentences; or poor grammar (e.g. "me want that red one" instead of "I want the red one").

Social skills

Human-to-human interaction is vital for developing emotional literacy and empathy. When caregivers label emotions, comfort children, and problem-solve with them, children learn to regulate their emotions and problem-solve too. With an innate ability to mirror others' emotions, children learn empathy through these interactions. Screen time, which lacks real social cues, can hinder a child's ability to mirror emotions and practise responding appropriately.

Attention

Research has shown that excessive screen use can result in overstimulation and sensory overload, which may lead to poor focus and a shorter attention span (SingHealth, n.d.).

Sleep

Screen time before bed can negatively affect sleep. Moving graphics, cheerful music and endless on-demand entertainment can push bedtime later and overstimulate the brain, making it harder to fall asleep afterwards. The blue light emitted from screens also disrupts the production of melatonin — the hormone responsible for sleepiness — heightening the risk of insomnia.

Physical development

Reduced physical activity from excess screen time can hinder physical development and health. Research has also found higher obesity rates among children with excessive screen time compared to those who spend less time in front of screens. Restricting screen time and ensuring enough physical activity supports optimal physical development.

Literacy

Because screen time influences attention and language skills, it can also result in lower comprehension and literacy levels. Balancing screen time with other activities is crucial for overall cognitive development.

How much screen time is appropriate?

• Children aged 0–18 months: no passive viewing
• Children aged 18–36 months: no more than 1 hour of passive viewing (UNICEF, n.d.)

Passive viewing refers to screen viewing without any adult co-viewing or interaction — for example, placing a child in front of the TV and walking away.

We understand that engaging children all day without any help from devices can be exhausting and challenging. The goal isn't perfection — it's balance. Swapping some passive screen time for shared play, reading, outdoor time, and everyday conversation gives your child rich opportunities to learn and grow.
