This is not a pressing matter as I'm not pregnant, but I've been thinking about this lately as we already used up our longtime favorite girl name on a puppy. We really liked the name Penelope/Penny after watching Lost but assumed we wouldn't have kids, so when we got a second dog last year there was no question that we had to name her Penny! Unfortunately we ended up rehoming her. So we've been wondering if we could use Penelope as a middle name if we have a girl someday, or if people would just think we're bonkers for reusing the name.
