For our first child DH was in the bath and thought of a name.
At the time I had also thought of a name.
Ended up his first and mine the middle name.
Found out after DS was born the first name was my great grandfathers
and the middle name was DHs great grandfathers name.
DDs name was chosen as an emergency she wasn't expected to live that night
and we wanted her to be christened. Didn't pick a middle name.
She survived and is now in her 40's and a mother of 3.
