Ignore all the dickheads op. I had the misfortune of telling Mn that I called my ds sonny. Apparently it’s ‘disgusting and vile’ and I’m ‘a bit thick’ for using it because it’s not even a name, it’s just the word for son. Never mind that it’s hundreds of years old and an extremely popular name in multiple countries 🙄
Mumsnet will only back traditional names. And SOME old person names. But only some. Definitely white names.
Nature names, modern names, quirky names, surnames, colours, adjectives, abstract nouns, anything from a Black naming tradition, anything coded "naughty child" (working class)... Mumsnet gets its judgey pants on. I find Mumsnet to be really valuable for a lot of things, but other stuff you must take with a gigantic pinch of salt.
I really don't think either you or the OP need to worry yourselves about what Mumsnet thinks of your kids' names. It is very very limited in this regard. I know of so many kids called Sonny or Sunny, and Leni/Lenni really isn't an unusual girls' nickname across many parts of Europe. They're lovely names.
