Okay, I'm going to change names here but please imagine a very similar situation.
My name is Christina but almost everyone day to day calls me Tina. I absolutely love a baby girl name and nothing else really interests me. The only problem is... it's Nina.
Is this acceptable? I can't decide whether people will people think I'm mad rhyming my name with my daughter's? Or, if no one uses mother and daughter's name together so it doesn't matter? Help!
