Meet Presley! Presley is a young girl who has a daily vlog and she vlogs on just about anything of interest to kids - American Girl dolls, toys, comic books, books, movies, and more. She has even done a video about the need to closed caption videos! Her videos have a lot of captioning gaps as it is a do-it-yourself effort, so it is recommended that you go to the videos listing page and look for the ones that have a CC icon.
