Sorry if this comes up twice - for some reason it didn't show last time.
DD1s first name begins with the same letter as my first name.
Most of the names I like for our next DD begin with that same letter, too, and I sort of feel as though I should steer clear of them, even though I like them, because there will be three females whose names start with the same letter in our immedaite family.
Even when I had DD1, people commented "oooh, it will be confusing when the post arrives..."
So if you were in this situation, would it bother you enough to avoid the names you liked?
Simples, my post comes addressed to Mrs. A. B Connor*, my daughter is Miss A. Z. Connor and if I had a son I wanted to call Adam or something he'd be Mr A Connor or have to have an initial that wasn't B or Z in the middle, so the prefixes sort it out for now, backed up by the initials. When they get old enough to have very private post, like bank statements, they will just have to make sure thier post comes with the right prefix and initials or risk Mum reading it.
I had the same initial as both my parents and we did get post sometimes addressed to C Pooter. You cannot always control what companies will put on their mailing lists.
I'd just avoid going as far as a family I know of J's - dad is J...., children are J[longer version of same name] and J[very similar female name], daughter married a man called J[same name, different spelling, as her father], and they have two children whose names both begin with J.
I know some people raise this as an issue with the post, however, things are increasingly moving to online billing, mobile comms, etc, so really how much post do we all get? Plus, I imagine it is a minor irritation rather than a disaster?
Personally, if your favourite names begin with the same letter as your/DD's name, I would go for it. I can't imagine in 15 years time you standing there, having opened the wrong letter saying "oh I wish I had called her something completely different" iyswim.
Just don't have a father and son with identical initials, both my hubby and his father are Mr P.J and it is confusing and was told in no uncertain terms when I knew I was having a boy it wouldn't be another P.J.
