Any player which will play only youtube playlist (parental control)

[rvsw]

I have an old phone which I am considering handing to my daughter to watch educational videos on youtube. The ideal way to use would be for me to set the videos in the playlist and then she can view only those videos. Is there an app that allows playing of only youtube playlists.
Thanks for any answers
