If so what were/are they ?
We had couple, like didn't want to use same intial as me or DH and, second time not same as DD1. Also ruled out 'noun' names eg Ocean even though I liked a lot of these, I thought in long term might not be appealing for the person who has it as a grown-up ( no offence to others who disagree)
Also one rule was nothing very very unusual or really weird that no-one had heard of, so to avoid the poor kid having to spell their name out all the time....
.......BUT in the end me and DH fell in love with one name when DD2 was born and gave her a v unusual name. We simply liked nothing else better.
SO did you have 'rules' ? Did you follow them ?? ?
