A new study from Tel Aviv University found that interaction between mothers and their toddlers is reduced by a factor of four when the mothers use their smartphones, which might damage the toddler’s development and have even greater and far-reaching consequences. The results of the new study, which was led by Dr. Katy Borodkin of the Department of Communication Disorders at the Stanley Steyer School of Health Professions, Sackler Faculty of Medicine of Tel Aviv University, were published in the journal Child Development.
