You’ll never really realize how much happens in the first year of life if you never researched! A baby is born with a functioning brain, and although the brain may be functioning correctly their brain is much smaller than ours and has lots of processes it will endure to reach a fully developed brain later in life. Synaptogenesis is a life-long process that starts soon after conception that runs through to the end of life. Exuberant synaptogenesis is the rapid acceleration in synapse formation, this happens from about 12 weeks after conception until about the eighth month after birth. Excessive screen time can interfere with this process and babies who spend lots of time passively watching screen may not be getting the experiences they need to form a wide variety of synapses causing them to prune away instead of being strengthened. Also, sight develops at a very rapid pace, a newborn can focus best on a distance of 20-40cm. Infants actively seek stimuli, habituate to the familiar, and respond more vigorously to changing
stimuli. According to Lightfoot (2018), a child is born with intrinsic predispositions that help make the process of visual inputs a bit easier. These predispositions include capacity to recognize pattern and differentiate between areas of light and darkness that contrast with one another. A screen holds a baby’s attention and gaze to one fixed point in space – they are not practicing the important skill of adjusting their focus to various distances. For this reason, early screen usage is thought to be associated with the development of myopia (a common vision condition in which near objects appear clear, but objects farther away look blurry). Early screen time can also affect the development of the full range of eye movements. Evidence suggest that
higher levels of screen time in young children are associated with higher levels of adiposity, more sleep problems and lower scores on measures of psychosocial health, cognitive development and motor development highlighting the need to intervene at an early age (Veldman et al, 2023) This is why it is very important to go by the world of health organization recommendations and refrain from using screens for babies under two.
