Can't decide and think they're too close for sisters (right?)
Nina is a family name, my DH's great aunt who is just lovely and really encouraged him in his pursuing his creative career when no one else did. She would be over the moon. DH would love to use it and I do like it.
But Isla has long been my absolute favourite name I love to say it, I love the way it looks, I love everything about it! But we have no Scottish connections at all. I'm not worried about popularity in that more than one at school, but as a Nicola born in the 1980s, I don't want a name that will necessarily date stamp my kid. (But isn't Isla a new classic?) DH does like it too (was on the list for DD1 as well) but probably prefers Nina for the family connection. He'll go with whatever one I pick.
We're also always talking about moving abroad (maybe a pipe dream though!), and I think Nina would be much easier in this respect. I'm not worried about the siren thing with Nina that's silly but I do worry it's a bit plain next to our DD1s name. Isla probably goes better with it.
Also our DD1s name has such deep meaning for us (was our midwife's name -- wasn't even on the list) that it's hard for me to just say "oh, I just liked the name."
But am I always going to wince when I hear the lovely Isla? Thoughts please!
