We’ ve all seen it … your two-year-old sees a photograph and instinctively tries to“ swipe” it. It’ s adorable, but it also shows just how naturally toddlers are drawn to screens. This makes it important for parents to be mindful of screen exposure and its potential impact on early development.
The dopamine response
It’ s easy to rely on screens to keep toddlers occupied – after all, nothing grabs their attention quite like a tablet or television. Every swipe and tap triggers instant responses: colours, sounds, and movement. This rapid stimulation prompts the brain to release dopamine, a chemical that plays a key role in our reward system and feelings of pleasure.
Dopamine can be addictive. When the screen is removed, toddlers may initially struggle to re-engage with slowerpaced real-life experiences. This is because their brains have become accustomed to instant responses, making ordinary activities seem less exciting by comparison.
The takeaway? Controlled and limited screen time is important to prevent toddlers from becoming overly reliant on fast, digital rewards for entertainment.
Social development
The first three years of life are critical for social development. During this time, the brain is laying the foundation for communication, emotional understanding, and relationships. Excessive screen time can limit opportunities for toddlers to engage in“ real-world” social interactions – playing, talking, observing facial expressions, and responding to tone of voice. These experiences help develop the frontal lobe, which is essential for interpreting social cues and building meaningful connections.
While occasional screen use is unlikely to cause permanent harm, it’ s regular or extended exposure that may reduce opportunities for these foundational experiences. Encouraging play with real people as well as engaging activities are key for healthy social growth. www. futuresa. co. za 23
