Playing with iPads and smartphones ‘severely stunts toddlers’ speech’
PUTTING babies in front of iPads before the age of two stunts speech development, a new study suggests.
In Britain children under the age of three spend an average of 44 minutes a day using smartphones and tablets but it is the first time researchers have shown it can impact language skills.
Researchers from the University of Toronto and The Hospital For Sick Children in Toronto found that every 30 minutes of screen time increased the risk of delayed speech by 49pc.
By the age of two to three, infants should be able to communicate in sentences of between three and four words. But those who spent the most time on handheld devices were found to struggle with communication skills.
Although guidelines exist for screen time, many parents do not realise that it also applies to handheld devices, the authors warn.
“Handheld devices are everywhere these days,” said Dr Catherine Birken, staff paediatrician at The Hospital for Sick Children.
“While new paediatric guidelines suggest limiting screen time for babies and toddlers, we believe that the use of smartphones and tablets with young children has become quite common.
“This is the first study to report an association between handheld screen time and increased risk of expressive language delay.”
The study involved nearly 900 children aged between six months and two years and was presented at the 2017 Paediatric Academic Societies Meeting in San Francisco.
Dr Birken said all screen media should be discouraged in children younger than 18 months.
A recent study by University College London found that screen time can also impact the sleep of infants, and possibly harm brain development.
The British study found that every hour infants spent on such devices was linked to 16 minutes’ less sleep.
Sleep is important for the development of the brain, especially during the first few years of life.
The researchers believe that blue light from screens can affect the bodyclock, disrupting circadian rhythms while the stimulation caused by the content of the games or programmes can cause psychological and physiological arousal.
