I think it generally fits the style of your other daughters' names. However, it does sound a little made-up to me. The nicknames are super cute though! :)
My first reaction, to be totally honest, was "ick". Next to the other names, it sort of fits and that kind of saves it. But I think you could do better, with an existing rare or even made-up name.
wolv: No worries. LOL. I know it's a bit over the top. Any ideas instead of this name? I am always happy for suggestions.
