I'm pregnant with baby no.4 (3rd girl) and can't decide between the above 3 names...
Alice - I really like but the 1st letter is the same as the 1st letter as one of my other daughters which isn't ideal, IMO. Also no decent nns...
Emilia - I love and also love Emi/Emmy but I dislike Amelia (irrational I know). I like Emily but know quite a few and I don't like it enough...
Beatrice - I love and also love Bea/Bebe but it's a little bit more unusual/old-fashioned than my other dcs names...I know it's "in" at the moment but the other 3 are classics/more popular..
