My due date is in one week and my husband and I need help choosing names. We do not need to leave the hospital without a name on the birth certificate. 
I need both a boy and girl name that goes well with the other sibling names [name_f]Caitlin[/name_f], [name_f]Elizabeth[/name_f], [name_m]Ethan[/name_m], and [name_m]Lucas[/name_m]. I keep pondering what sister name sounds best with [name_f]Caitlin[/name_f] and [name_f]Elizabeth[/name_f]. What brother name sounds best with [name_m]Ethan[/name_m] and [name_m]Lucas[/name_m]? What goes well with all of the siblings together? Yet, I am still stressed without a definite answer in mind. Our family uses the full first names of our children and never nicknames. Our two syllable last name is Drennan. Below are some of the names that we have been considering lately. However, I am open to a few suggestions too. Please share with me your thoughts on what names you think are best. Thank you for your help!
Girl Names:
[name_f]Abigail[/name_f]
[name_f]Amelia[/name_f]
[name_f]Caroline[/name_f]
[name_f]Charlotte[/name_f]
[name_f]Olivia[/name_f]
[name_f]Sophia[/name_f]
Boy Names:
[name_m]Jonathan[/name_m]
[name_m]Liam[/name_m]
[name_u]Noah[/name_u]
That’s funny, my name is [name_f]Caitlin[/name_f] [name_f]Elizabeth[/name_f]! Your children’s names flow together really well.
For girls, I love [name_f]Amelia[/name_f] [name_f]Charlotte[/name_f] as a combo. I think [name_f]Caroline[/name_f] would be nice, but it’s a little too close to [name_f]Caitlin[/name_f].
For boys, I think [name_m]Jonathan[/name_m] suits the sibset the best, but it shares an ending with [name_m]Ethan[/name_m], so [name_u]Noah[/name_u] is my favourite in this case.
Suggestions:
[name_m]Nathan[/name_m]/[name_m]Nathaniel[/name_m]
[name_m]Samuel[/name_m]
[name_m]Benjamin[/name_m]
[name_m]William[/name_m]
[name_m]Jack[/name_m]
[name_f]Lily[/name_f]/[name_f]Lillian[/name_f]
[name_f]Emily[/name_f]
[name_f]Penelope[/name_f]
[name_f]Lucy[/name_f]
[name_f]Hope[/name_f] this helps!
I agree that [name_f]Caroline[/name_f] is a little close to [name_f]Caitlin[/name_f] and [name_m]Jonathan[/name_m] to [name_m]Ethan[/name_m], so I’d take those off your list. I’d probably also take off [name_m]Liam[/name_m] and [name_f]Charlotte[/name_f] because they have the same starting letter as other sibs. I’d go for [name_f]Olivia[/name_f] or [name_f]Sophia[/name_f] from your remaining girl names because they are less susceptible to nicknaming.
Some other possibilities:
[name_f]Caitlin[/name_f], [name_f]Elizabeth[/name_f], [name_m]Ethan[/name_m], [name_m]Lucas[/name_m], and
