Thanks all. Sorry not to have posted earlier but until now all I got was a Siblu advert when opened any thread!
Glad there's such a positive reaction to the name; DH and I had thought we were down to a fight over two names (Nina or Elizabeth) until we saw Definitely Maybe on DVD; didn't like the film but the little girl is called Maya and we both liked the name
If we go for it we'd definitely pronounce it Ma-ya (July baby, not a May one puddock )
The reason for the query on spelling is that I'm usually very pro the 'right' spelling of names, just in this instance both spellings seem fairly equally common. I suspect that 'Maya' would be easier for strangers to pronounce/spell correctly, but also that 'Maia' is the 'classic' spelling (like Grumpyoldcaaaaaa's DD though I suspect we'd get a lot of 'Mia'). We have no Mayan connection, so no argument either way there!
Anyway, thanks again. I have lurked on Baby Names threads before and there seems to be an unusual degree of consensus that this is a nice name
