Last week we heard about YouTube's new app for little tykes, and now, it's ready to go to work. YouTube Kids is available on iOS and Android, delivering access to shows and music (Thomas the Tank Engine) with options for learning or exploring (Reading Rainbow), too. As you might expect, there are parental controls to keep tabs on content, sound levels and screen time, and items that don't need to be futzed with by children (comments, etc.) are absent. What's there, though, is a tiny finger-friendly interface of large images for easy navigation. If you're willing to hand your iPad or Nexus 9 over to junior, head over to the appropriate app repository to download.
