DD2's first name is Fiadh ("Fee-ah") and, as with DD1, we decided to wait and get to know her before choosing a second name.
Well, she was born in the summer, has golden hair and rosy cheeks, is a laughing, smiley, chatty little ray of sunshine, and spends a lot of her time being deafeningly cheerfully noisy for fear her 2 year old sister would steal too much of our attention. Hence the theme we're going with for her middle name.
We speak Irish at home and love Gaelic names in general. We chose a Welsh one for DD1 as its meaning fit so well.
