How Early Screen Exposure Hinders Children’s Speech Development – Paediatrician
Early, prolonged screen exposure may contribute to childhood speech delay, especially as clinicians now see more cases compared with a decade ago, a Paediatrician, Dr Leo Odudu, has warned.
Speaking to the Newsmen in Lagos on Sunday, Odudu linked rising speech delays to widespread smartphone, tablet, and TV use, describing screens as “the great pacifier” when parents substitute devices for direct communication and teaching.
According to him, clinicians are increasingly managing children with speech delay, unlike 10 to 15 years ago, noting that studies showed that four to five per cent of children under four years globally had speech delay from different causes.
He explained that language development begins in infancy through babbling and caregiver interaction, with meaningful words expected around twelve months and rapid vocabulary growth between twelve and eighteen months.
He said concerns included poor articulation, limited vocabulary and unrealistic expectations by parents comparing children with siblings or neighbours.
“Researchers note excessive screen time can impair brain white matter development, confuse emerging language patterns, and produce poor articulation, limited vocabulary, weakened attention, and social interaction difficulties”.
The paediatrician said speech delay was previously linked mainly to birth asphyxia, severe jaundice and congenital syndromic defects.
He said children with normal birth histories were now increasingly presenting with delayed speech development.
Odudu said early exposure to smartphones, tablets, computers and other screens was a common factor identified in many cases.
He said digital devices supported education, communication, work and information access but could be harmful when misused by children.
Odudu said language development begins in infancy through babbling and cooing during the first three months of life.
He said children should begin saying meaningful words at about 12 months and develop 10 to 50 words between 12 and 18 months.
According to him, children learn language through hearing, repetition, interaction and communication with parents and caregivers.
Odudu said some parents relied on cartoons and educational videos instead of serving as their children’s primary language teachers.
He said speech development depended on hearing ability, pitch, intonation and diction, while some babies were exposed to screens from three months.
The paediatrician said many parents used screens to distract children during feeding, describing gadgets as “the great pacifier”.
He warned that prolonged screen exposure increased speech delay risks, with some infants spending four to six hours daily on screens.
Odudu said excessive screen use had been linked to impaired white matter development affecting language and literacy networks in the brain.
He said the effects of excessive screen exposure could persist until children were about eight years old.
According to him, children exposed heavily to cartoons could become confused by cartoon language, local dialects, Nigerian English and crèche communication styles.
He said such language confusion could make it difficult for the developing brain to process and adopt a communication pattern.
“At best, the infants resort to gibberish or cartoon language or just fail to make any meaningful sound at age two,” he said.
Odudu said children in rural communities with limited gadget exposure often acquired local dialects easily and communicated effectively by age two.
He identified poor social interaction, tantrums, weak attention span and difficulty with group play as other consequences of excessive screen exposure.
Odudu said some children ignored their names but responded immediately to favourite cartoon sounds, causing concerns about hearing impairment.
He said countries including Australia and the UK had introduced policies to restrict children’s access to social media and mobile phones in schools.
Odudu said global efforts were increasingly focused on reducing children’s contact with gadgets to support healthy development.
He cautioned against readily diagnosing children with autism spectrum disorders without considering their need for more interaction with parents and siblings.
The paediatrician urged parents to reduce children’s unnecessary screen exposure and communicate with them regularly.
He advised parents to read to their children and speak the language they wanted them to acquire.
Odudu said phones and tablets remained valuable educational tools but their misuse posed risks to children’s intellectual, social and psychological development.
Sharing recovery stories after reducing screen use, some parents noted that they did so by replacing videos with talking, reading, songs, and play that improved children’s speech, response to names, and social engagement significantly over time.
A mother of two, Mrs Blessing Okafor, said her first child became unusually quiet after prolonged cartoon viewing on a mobile phone.
Okafor said she initially gave the child a phone to keep him occupied while she attended to household chores.
“Whenever I collected the phone, he would cry and demand it, but he was not responding much when we called him,” she said.
She said the family reduced the child’s screen time after consulting a health worker and introduced talking, reading, outdoor play and family interaction.
“Gradually, he began to use more words, call names and respond better when we spoke to him,” Okafor said.
Another parent, Mr Chinedu Eze, said his daughter’s speech improved after the family stopped allowing her to watch videos during meals and before bedtime.
Eze said the family replaced screen time with bedtime stories, songs, picture books and conversations about the child’s day.
“We realised that she needed us to speak with her more, not just allow cartoons to speak to her,” he said.
