Go for it spareparts. When it comes down to it, when you have your lovely little DD and they are adorable, no one is going to be like when you say her name, and if they do, it won't last long. Even the most ridiculous of names become normal once they've been used a few times by people - the novelty soon wears off.
You are brave though to post a name you love on here - I never would as it would make me pathetically miserable to hear everyone slagging off a name I loved. I'm such a sensitive soul...
