How late is too late to change baby's name?

[SomethingBeginningWithX]

DD is just over 6 weeks old. We were choosing between 2 names and went back and forth until we registered her, but a few weeks on from that and I'm still feeling undecided!

The problem I'm having is that the name we've chosen, although lovely, can be pronounced in 2 ways and it feels like everyone uses the pronunciation we don't. I'd rather not say the name but it's along the lines of Esme. Every conversation goes:

Oh what's her name?
Es-may
Es-mee, how nice...

Or Maya

Her name is My-ah Jones
Ok and when was May-ah born?

They are just examples but I feel like almost no one says her name the way I'd prefer. It's really, really getting to me and bringing me down.

I should add I'm suffering with PND so not sure if I'm making a mountain out of a molehill. I don't trust my own judgement anymore and feel exhausted and deflated by the whole thing. I've almost got to the stage I don't like the name anymore DH is mildly annoyed by it but not overly so, he's much more laid back than me anyway.

Anyway, would you think someone was an absolute idiot for changing a baby's name at 6 weeks or more? Will people get used to it?

I feel really embarrassed that I've totally messed up naming her. She's also been bought a few gifts with her name on them and if I was to change it I'd feel really bad about those.

Help!

I think you need to let it go. My name, Grant, has two very common pronunciations - Gr-ant (as an American would say) and Gr-aren't (British/traditional Australian accent). Both myself and my parents live in Australia and were all born there but their pronunciation is Gr-ant, possibly due to the increasing influence of American culture here. Mum, without fail, will always correct people who say Gr-aren't, including Nanna who, for the 43 years that we were both alive, was either ignoring Mum's disapproving comments or just liked to stir her up (or perhaps both on different occasions, who knows?)

I answer to both pronunciations, often without even noticing which one is used and, given that people usually stick with the same pronunciation for similar-ish sounding words like "dance" and "France", I'd say that about half of the time my name is said "wrong". Given that my name is a common English word as a noun and verb, on top of being a proper noun, I'd have so many more grey hairs if I was bothered by the pronunciation of my name.
