Mobile phones for children: the impact on child development

We are increasingly connected to the digital world, and in turn, young people are gaining access at an ever-earlier age.📱

Nowadays, children develop a daily habit with technology even before they start school, which makes us wonder: 

👉 Is this really a positive thing? 

👉 Does it impact child development in any way?

Today, we will explore this topic in greater depth, understanding why this is a concern for adults.

Mobile phones for children: why is early access a concern?

The first years of life are deeply crucial for a child. The brain is in constant development, and children are shaped by experience, movement, social interaction, and play!

However, the mobile phone disrupts this dynamic, creating dependencies that end up replacing experiences that are essential for healthy and full child development.

The central issue is not just about screen time, but also about the appropriate age for a child to be exposed to this technological reality. Devices like tablets, computers, and mobile phones provide rapid, intense, and constant stimuli that a child's brain is not yet prepared to process.

📖 Studies even reveal that excessive screen time affects the structure and function of the brain , impacting the frontal lobe—a vital part of the human brain for various areas of life, from well-being and academic and professional success to social skills. 🧠

What are the consequences of excessive mobile phone use

The consequences of early and excessive mobile phone use are not always obvious to parents. However, it is increasingly important to raise awareness about the medium- to long-term effects that impact not only childhood and adolescence, but also adult life. These often include:

• Attention and concentration difficulties
• Increased hyperactivity and impulsivity
• Lower frustration tolerance
• Sleep disturbances

📖 A recent study involving more than 100,000 young people between the ages of 18 and 24, which analyzed the impact of getting a mobile phone before the age of 13, provided us with relevant findings in this regard. They found that there is a strong correlation between the age at which a smartphone is acquired and the severity of symptoms in adulthood. These symptoms include:

• Suicidal thoughts
• Aggression
• Feelings of detachment from reality
• Increased intrusive thoughts
• Low self-esteem, emotional control, and resilience.

It was also concluded that mobile phone use before the age of 13 increases the risk of cyberbullying and significantly impacts the development and acquisition of social skills, resulting in a tendency toward isolation. Additionally, early mobile phone use is associated with sleep disturbances – which are closely linked to early access to social media.

What are the downsides of mobile phones? 

Beyond the consequences for well-being and mental health, the disadvantages of mobile phone use become even more serious when there is no control or supervision by adults, OR when they use the phone as a means to calm, distract, or occupy the child. 

These small “habits” promote:

• Development of digital addiction 
• Decrease in face-to-face social interactions, resulting in increased isolation behaviors 
• Greater exposure to content that is inappropriate for their age
• Decline in academic performance

The mobile phone can indeed be a quick fix for situations involving a child's crying, frustration, or irritability. However, at the same time, this prevents the child from learning how to manage their own emotions in a healthy way. 

Therefore, the solution lies in creating limits, rules, and constant supervision. 

How much time should I spend on my phone per day? 

🤔 As we have seen throughout this article, the answer is very simple: at early ages, the less exposure, the better.

• Screen time is not recommended for children under 2 years old. 
• Children between 2 and 5 years old should be limited to 1 hour per day. 
• For children over 5 and teenagers, the recommended limit is 2 hours per day.

Above all, we must remain vigilant and observe the impact that the use of these devices may have on a child's behavior, sleep, and mood. 🔍

How to break a phone addiction?

This can be a difficult process, but some practices can help reduce this dependency:

⌛ Gradually reducing screen time

Start by setting a usage schedule and do not allow for flexibility. 

📋 Creating predictable routines

By establishing a routine that includes time for school, family, play, homework, and screens, you prevent the child from being exposed to a screen for long periods.

🪁 Encouraging play and movement

Children were born to play, run, and socialize with other children! It is important to encourage real moments of fun that promote physical activity and the strengthening or creation of emotional bonds. 

🏠 Creating "screen-free" zones at home

It is important to establish areas where the child understands that it is not appropriate to use a phone. 

For example:

• By banning phone use in the study area, the child understands that it is time to focus solely on schoolwork.
• By banning phone use in the bedroom, the child understands that it is time to play with their toys or rest, without digital interference. 

👫 Active parental presence

It is equally important that it is not just the child who has limited phone time. Parents must also lead by example and create this habit, consequently investing in family time!

How to choose the right first phone for children:

As children grow, it is natural for the need for an extra means of contact, such as a mobile phone, to arise. However, choosing their first smartphone should be done carefully. Beyond calls and messages, it should allow for:

• Active parental control 
• Limited internet access - to prevent access to content inappropriate for the child's age and development
• Drop resistance

Once the child gets a mobile phone, parents should also:

• Limit access to social media 
• Limit access to games 
• Limit/reduce notifications

⚠️ We should view a child's first mobile phone as an extra means of communication, not as a source of entertainment. 

Toy mobile phones: are they a safer alternative?

For younger children, a toy mobile phone can be an alternative. Toys that simulate the adult world allow for healthy childhood growth, while also opening doors to the development of imagination, language, and social interaction! 👶✨

Final Considerations

🔸 Devices like tablets, computers, and mobile phones provide rapid, intense, and constant stimuli that a child's brain is not yet prepared to process.

🔸 Early and excessive mobile phone use can have consequences not only for childhood and adolescence but also for adult life.

🔸 The disadvantages of mobile phone use become even more serious when there is no parental control and supervision, OR when they are used to calm or occupy the child.

🔸 At early ages, the less screen exposure, the better.

🔸 Certain practices can help reduce digital addiction, especially when applied from an early age.

🔸 However, the choice of the first smartphone must be thorough, and parents should limit access to the internet and games, as well as reduce notifications.

🔸 Mobile phones should be viewed as a means of communication, not as a source of entertainment.

🔸 For young children, a toy phone can be an interesting alternative to explore.
