Exclude Playlist from Listening History / Discovery

I have a playlist on my Apple Music that is used for my son. Mainly children's songs etc. When I just ask Siri to play me some music or use the Listen Now feature I keep getting songs thrown in that are related to this playlist. Is there a way to exclude certain playlists from my listening history or whatever algo apple uses to populate my Listen Now section? I don't want to turn off listening history completely as I use this feature to discover new music.
