DS is Isaac and we've just found out our twins are pink 
DH and I cannot agree on any girls names and tbh I don't feel I love any girls names.
I like names ending in 'a':
Olivia - too common?
Ava - ditto
DH is set on Nuala but I've gone off this name.
Lucy is a possible which obv breaks my 'a' rule, again I'm worried she would be one of many.
Any suggestions??
