Birthing Wishes

Is there a special phrase you say when someone has given birth in Greece, as our consulting engineers wife has just given birth and I would like to congradulate them in Greek style.

First of all hi!!!
Well its not like a special phrase or something like that but we say "να σας ζήσει".its something like: may it live in english!But its what anyone says for birth congratulation
so lets go to the pronunciation now.i ll give you each letter alone.

Ν ν  [capital and small greek letters here]
(nu)
• like n in note

Α α
(alpha)
• like a in father

Σ σ ς σ and ς are small but ς is used only as the last sigma in a word
(sigma)
• before β,γ,δ,ζ,μ,ν,ρ - like z in zoo
• otherwise - like s in set

Ζ ζ
(zeta)
• like z in zone
   
Η η
(eta)
• like ee in meet, but clipped short

ΕΙ ειits two letters but in this form they sound like eta
• like ee in meet, but clipped short


*end of the class:).as you see some letters are the same.you got everything you need.so it should be like this: "na sas zeesee".
I hope that helped otherwise i m still here:)
{oooppps.. i forgot to mention pronuntiation(N like n in note and so on) is in english cause i just saw that you are from wales!!2.i suppose they are couple otherwise i have to change a word.and i really wanna be there for a short time period at least!see you around...i hope!ohhh send my wishes to them too:)}
