My sons name is shortened to Ed or Eddie about 70% of the time, is it too samey to have a daughter with a name which would likely shorten to Ellie or Ella? The long versions don't sound similar at all (except the first sound).
When naming my first two children I was adamant I didn't want them to have the same initials but it doesn't bother me so much this time..
(my naming approach is fairly unusual but with a more common nickname)
