Mayjorly regretting my son's name.

[MissMoon10]

I can't even sleep properly he's our PFB, so I just hate it when I mess up.

His name is Greyson (we assumed Grey would be his NN?)

Oh no, he gets 'Greys' (pronounced exactly like Grace). I know it's probably a very minor thing, but I feel like I've messed up massively. People do assume his name is Grace because of how many people use Greys. I'm sure in different accents it sounds different to Grace, but where we are they sound exactly the same.

I'm so fed up. I know it's silly but I really can't help it.

Do you happen to live in Australia? I can kind of imagine the Aussies shortening Greyson to Greys.

I can see it's worrying you but I agree with other posters, stick to your guns and just keep correcting people. Introduce him as "Greyson but we call him Grey" and correct people who are already using the annoying nickname.

In UK you can legally change their name quite easily up to a year of age...
But I agree with everyone else, just say what you prefer and people will follow. And ignore those that don't!
