Hello,
I wanted to make a card to say 'To my goddaughter, on your Christening day' but in standard Irish.
Could anyone advise if 'Do mo Iníon Bhaistí, ar lá do Bhaiste' would be correct?

Thank you,
Fiona

Almost

Do m’iníon bhaistí, ar lá do bhaiste

(mo [= my] is shortened to m’ before vowels. And there is no need for capital letters)

Thanks so much, your explanation is really helpful!

Fiona

As an add on question can I ask how to change it to 'To our goddaughter' ?

And also would the same sentence for godson be
'Do mo mac bhaistí, ar lá do bhaiste'
leaving the mo as mac doesn't start with a vowel?

Sorry for the basic questions, learning as I go!

To our goddaughter: D'ár n-iníon bhaistí

Godson: Do mo mhac baistí, ar lá do bhaiste

Here are also some dialectal forms:

Munster: Dom' iníon bhaistidh, ar lá do bhaiste, d'ár n-iníon ..., dom' m(h)ac baistidh, ar lá do bhaiste
Connaught: Do m'inín (or maybe go m'inín) ar lá do bhaiste, d'ár n-inín ... (or maybe g'ár n-inín?), do mo mhac baiste, ar lá do bhaiste
Ulster: Do mo nighean/níon baiste ar lá do bhaiste, d'ár nighean/níon ..., do mo mhac baiste ar lá do bhaiste
