Name confusion

[Superoverthinker]

So I have a dd who was named last month and birth was registered.
Her middle name is a name that I'd been calling her all the way through pregnancy but my inlaws didn't like it so we kept it as a.middle name and chose our second choice name as her first name.
Turns out they're not that keen on that either.
I cant call her by her first name as although I like, it doesn't seem liker her iykwim..I keep calling her by her middle name and so do most of my family and fiends.
I think we should get her name changed but my dh says keep them the same and just call her by her middle name.
Would that be confusing though?

I Do like the first name just to say and my in laws DIDNT choose it we did but originally the names were going to be thr other way around until they heard the first name then that out my dh off although he won't admit it.
My inlaws don't call the baby anything they refer to her as baby girl so I'm not bothered what they think anymore.

But anyway think I shall swap the names around
