The research is very clear. Smart _____ do not belong in the hands of toddlers. They need to hear, see and practice speech sounds with an engaged speech partner.
Excessive screen time in toddlers is linked to speech delays and slower brain white matter development. Studies show that handheld screen time, increases risk of speech delays by 49% in toddlers.
Toddlers learn language through active engagement with their environment and caregivers. Screen time, particularly passive viewing, limits opportunities for back-and-forth communication, which is essential for language acquisition.
When children are watching screens, they miss out on crucial social cues, facial expressions and tone of voice that help them understand language and communication.
White matter in the brain is responsible for communication between different brain regions. Studies have shown a correlation between increased screen time and slower white matter growth, potentially impacting overall cognitive development, including language skills.
Real-world experiences, like playing with toys, exploring nature, and engaging in imaginative play, stimulate various areas of the brain and support language development. Screen time can replace these enriching activities.
Expressive speech delays, where children have difficulty communicating their thoughts and needs, can lead to frustration and behavioral issues. These delays can also have long-term consequences for literacy skills in school.
