We really struggled with girls names for DD1 and now we're going through the same struggles with DD2 (due July).
We eventually landed on Emily for DD1 (yes popular but also classic and we love it). But completely stuck on DD2. So far we have:
Clara (probably our top choice)
Laura (underused I think these days but I know loads of Laura my age!)
Zoe (my least favourite but DH likes it)
I like classic names. Quite old-fashioned taste. DH likes short names and he would happily use a nickname as a first name (doesn't see the need to have the long name on the birth certificate).
Names ending in S and T sounds run into our surname so they don't work.
All ideas welcome!
