Just that really - changed the names slightly but think along those lines. Dd's name would be a shortening of a 'full name'- think Lillian but known as Lily - and mine is also a shortening so our full names would be very different - but is it going to sound too silly in everyday life to both use two syllable names with the strong 'l' sound in the middle? I only have 7 weeks to go so I may be entering the overthinking stage....we've had our girl's name picked for so long!
