My cousin (who I rarely see, but fb chat now and again) has a daughter called Amelia but is always known as Millie. I don't think I've seen her daughter for a good two years. Dp really loves the name Amelia. Would it be wrong to use it? I can imagine various family members getting arsey as it's already in the (extended) family. I'm not due until April so plenty of time to think I suppose.
