Taking to Mumsnet to ask for opinions, the woman explained that her and her husband love the name, but 'chickened out' of using it when their first son was born.
"My husband and I have loved this name since conceiving our first son," she wrote.
"We really love flower names for boys, Lupin is edgy and unique, it also has the more masculine meaning of 'pertaining to the wolf'. Could be shortened to Lu or Louie.
"We chickened out of using it last time because we got a few negative comments and thought it was a bit TOO unusual but on the other hand it could be paired with a very ordinary middle name that he could use if he preferred when older.
"I found a post on here from a few years ago with horrendously negative feedback so I'm not expecting much here but I thought I'd put it out there again anyway to test the waters! So what d'ya reckon?"
The mum certainly had a mixed response, with some loving it while others thought it was 'a joke'.
Many commented on the Harry Potter connection, with Remus Lupin being a fictional character in the series.
One person wrote: "I'd think you were Harry Potter fans. I like it though."
Another said: "I like it, I would assume you were Harry Potter fans rather than anything to do with plants."
However, most had the totally opposite response, with one person commenting: "I don't want to come across rude but it sounds like an illness? I don't think it's a good idea personally. It just doesn't even really feel like a name."
Another said: "You are joking?"
A third wrote: "Really not," while a fourth said: "I’d think you are massive and slightly cringy Harry Potter fans. Yes the flowers are lovely, but I think the Harry Potter connection is still way too strong."
"Does not come across as edgy at all. It just seems like the sort of name two Harry Potter obsessives would give a child," said another.
Another added: "Absolutely not. It's just awful. I can't believe you are even considering it (esp more than once!)."
Yikes. What do you make of the name?
