It looks very pretty spelled out (as does
Caitlin) but the sound of kay-lin is rather trendy. I think that this spelling should actually be pronounced kay-leen because it's Irish and means 'girl' like
Colleen but if you like in the USA you can very easily get away with the kay-lin prounciation. It doesn't sound or look uneducated infact I think this spelling is rather classy! I do like it, a lot! :)
How does it sound with your son's name? What is your son's name?
