Anyone got any thoughts about whether to hyphenate the child's surname with both mums last names? Does it make any difference if you do or you don't? My partner and I both have surnames that are averagely long, and usually need to be spelt out letter by letter over the phone, so is the equality of a double barrel surname worth it? If we have one of our surnames as a middle name instead, are there any disadvanatages to that option?a
