Due with #3 in [name_u]July[/name_u]. We don’t find out the gender before hand.
Our daughter is [name_f]Ellie[/name_f] [name_f]Kate[/name_f].
My question, is [name_u]Lexi[/name_u] too similar to [name_f]Ellie[/name_f] or are they different enough? 
I can’t decide.
Our other options are [name_f]Olivia[/name_f] and [name_f]Caia[/name_f]. Middle name will be [name_f]Ann[/name_f].
Our son’s name is [name_m]Titus[/name_m].
Thanks!!
I quite like [name_f]Ellie[/name_f] and [name_u]Lexi[/name_u] together. I dont find them too similar.
I think [name_u]Lexi[/name_u] works well with [name_f]Ellie[/name_f], and [name_u]Lexi[/name_u] [name_f]Ann[/name_f] is cute! I like that [name_u]Lexi[/name_u] mimics the nickname-y style of [name_f]Ellie[/name_f], but I think they are both substantial enough on their own! I think the [name_u]Lexie[/name_u] spelling is cute, too, but it may mirror [name_f]Ellie[/name_f] more than you prefer.
I love [name_f]Olivia[/name_f], despite its popularity. [name_f]Olivia[/name_f] [name_f]Ann[/name_f] is pretty, but seems quite traditional next to spunky [name_f]Ellie[/name_f] [name_f]Kate[/name_f]. Although, [name_f]Ellie[/name_f] and Livi are super cute together.
[name_f]Caia[/name_f] is not my style, and I don’t think [name_f]Caia[/name_f] [name_f]Ann[/name_f] flows well.
I’d say use [name_u]Lexi[/name_u] if you love it, but [name_f]Olivia[/name_f] is a close second! 
I think [name_u]Lexi[/name_u] and [name_f]Ellie[/name_f] are great together. [name_u]Lexi[/name_u] my favorite of your options, but I also like the suggestion of Livi for you.
I think [name_u]Lexi[/name_u] and [name_f]Ellie[/name_f] are perfect together! They aren’t too similar in sound but are lovely nickname type names.
I also think [name_f]Olivia[/name_f] [name_f]Ann[/name_f] is lovely, with NN [name_f]Liv[/name_f] or Livi.
I think [name_f]Ellie[/name_f] and [name_u]Lexi[/name_u] work fine together. I little similar for my own taste but not a dealbreaker, and they feel more like sisters than [name_f]Ellie[/name_f] and your other choices. (Though if you like [name_f]Olivia[/name_f], maybe [name_f]Liv[/name_f] would be appealing?)
I appreciate all your opinions! I do love the nickname Livi. Not sure my husband would go for it for a first name but maybe. Thank you!!
[name_u]Lexi[/name_u] and [name_f]Ellie[/name_f] go well together but if its too samey to you you can always go with [name_f]Lexa[/name_f]
[name_f]Ellie[/name_f] and [name_u]Lexi[/name_u] sound perfect together! I quite like the idea of [name_f]Ellie[/name_f] [name_f]Kate[/name_f] and [name_u]Lexi[/name_u] [name_f]Olivia[/name_f] too?
I think [name_u]Lexi[/name_u] is plenty distinct from [name_f]Ellie[/name_f]. They share some sounds, but in a different order, and the “x” in [name_u]Lexi[/name_u] really helps distinguish them. [name_f]Ellie[/name_f] [name_f]Kate[/name_f] and [name_u]Lexi[/name_u] [name_f]Ann[/name_f] make perfect sisters, both with short, sweet names. One note- Would you consider [name_f]Gaia[/name_f] instead of [name_f]Caia[/name_f]? I think that [name_f]Gaia[/name_f] would go exceptionally well with [name_m]Titus[/name_m].
