So we were previously settled on Saffron Celyn (last name begins with W), but last night we were talking names and realised that we both prefer it the other way around - Celyn Saffron W___. (Celyn is Welsh for "holly", it isn't something we've made up in case anyone's wondering!)
The only issue is, we hate the nickname "Cel" or "Kelly" - we much prefer Callie. Calyn isn't an option because that IS made up, but would it be acceptable to have her official name as Celyn, which she can use when she's older/whenever she wants to - but we call her Callie, and hope that others will pick up on it?
