OP, you do need to think through the fact that you are not just naming a baby.
Stormi is cute, I suppose. Of course it makes me think Kardashian and 'no way' but what really needs to be considered is what happens when the cute baby grows up.
Stormi in infants school - cute.
Stormi in juniors - less cute but ok. I've taught a Storm before who was lovely.
But I've also taught children who have wanted to change their name by the time they were year 6 to be called by their 2nd name or a more formal version of their name because they don't like the cuteness and they feel they were growing up.
And then high school! High school is rough for kids with unusual names. My name is pretty unique and I was bullied for it. First day someone laughed at my name and although I like it now, I will never forget the embarrassment.
Then as an adult - would YOU want to be called a cutesy Stormi? Would you appreciate your name being Stormi if you were a teacher, policewoman, lawyer, ANYTHING?
Go for it as a middle name and choose to call your DD by that name if you really must, but give them a first name that they can grow into.
Plus your child will, like I was, be one of those who NEVER EVER sees their name on any personalised items you can buy that kids like.
