I prefer [name_f]Arielle[/name_f] [name_f]Hope[/name_f]! It’s very sweet, goes well with your other children’s names, and is less common than [name_f]Alexandra[/name_f]. I’m not a big fan of the name [name_f]Alexandra[/name_f] due to how common it is, and the nicknames. I think [name_u]Alex[/name_u] seems plain/common next to the names of your other kids.
I prefer [name_f]Alexandra[/name_f] nn Alexie, [name_f]Lexa[/name_f] or [name_f]Alexa[/name_f]. I think [name_f]Arielle[/name_f] blends too much into the other names. But they’re both good options!
I like [name_f]Alexandra[/name_f] [name_f]Hope[/name_f] too.
