YouTube Kids was created to make it easier and safer to explore videos online. Kids can learn songs, watch shows, and everything in-between. You can control what your kids watch by handpicking the channels and videos they watch. If you find a video that you don't want your child to watch, you can simply block it. Another great feature is the app keeps a timer on your kids watch time so you can put a limit on how much your child watches. YouTube Kids is completely free and fun to use.
