Remove song from stream history/ignore certain streams

Context: my Spotify is linked to our Alexa so we can play music, but this does mean that my little girl uses it frequently to listen to nursery rhymes, such as “Row row row your boat”. As is the way with children, these are played on repeat several times each day, and my stats now show that my top song of the year is a child's nursery rhyme.

I'd love to be able to remove these from my streaming history so that my account is only for what I've listened to, without having to unlink my Spotify account from the speaker, as this would mean my little girl couldn't use it for this purpose anymore.

I'm sure I'm not the only parent on stats.fm who has this issue - even if I could tell the app songs or artists to ignore streams for, that would be really helpful?
