Using a name very similar to DD1's middle name...

I think there lovely. I'd go for it if you both love it.

Thanks for the reassurance girls, we really do like the name but its not 100% set in stone yet.

i think if anything it will give both sisters a lovely tie together of their names

i know of a family who named their daughters Eva and Ava, not twins. I think that's a bit weird, but using Eva as a first name while having Ava as a middle name of DD1 is fine, i think. I actually think it's rather nice
