Results of a study published in November 2019 [1] actually show a structural difference between preschool age children who experience a lot of screen time and those who don&amp;#x27;t. Myelination is reduced in the former.  Myelination of brain white matter supports language and literacy skills.&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;jamanetwork.com&amp;#x2F;journals&amp;#x2F;jamapediatrics&amp;#x2F;article-abstract&amp;#x2F;2754101&quot; rel=&quot;nofollow&quot;&gt;https:&amp;#x2F;&amp;#x2F;jamanetwork.com&amp;#x2F;journals&amp;#x2F;jamapediatrics&amp;#x2F;article-abst...&lt;/a&gt;</text><parent_chain><item><author>pier25</author><text>It totally is.&lt;p&gt;I worked in EdTech for the past 4 years and was in contact with the education world.&lt;p&gt;Digital devices are harmful to younger kids.
