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

I think it is perfectly fine. Eva is a beautiful name, and I love the combo Eva Jade.

Eva is gorgeous. I'm not 100% about it with your surname though - too many vowels?

My middle name is Linda, and both my parents wer ready to all my sister Belinda. They changed it a few hours after she was born though.

I think they are both great names, and really hw often do you call kids by full name?

Go for it.

[Mildez]

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

[Isadora]

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
