Baby name etiquette?

DH and I love a name, I have told him a few times now that the name is the same as a friend’s son’s name.

We aren’t going to find out the gender of little one, so it may not even be an issue, but every time we run through names DH always comes back to it and says “what about xxx? I really like that name”. And I have to remind him again.

The only reason I know it’s their baby name is I had a feeling someone had chosen it for their little one, so checked their name announcement - along with many others - and it was there.

We see these friends once, possibly twice a year, as part of a big group i.e. our annual dog walk.

The name is currently in the UK top 20 and US top 5 names.

Would you say the name should be completely off limits?
