A new study says the amount of screen time a young child gets has a direct affect on their sleep.
The study published in the journal, Nature, says babies and toddlers lose 16 minutes of sleep for every hour they spend using a touchscreen.
Researchers say that lack of sleep could have a negative effect on emotional and social development down the line.
The survey found that 75 percent of babies and toddlers use a touchscreen every day.
While the links between smart phone use and lack of sleep are still being studied, researchers say over-stimulation likely plays a role.
