I really like the name [name]Susannah[/name], it’s definitely growing on me as a future contender. The thing is, nickname wise apart from [name]Susie[/name], [name]Sue[/name] or [name]Anna[/name], there aren’t very many options out there.
Could Sansa work as a valid nn for [name]Susannah[/name] do you think?
I think Sansa would work.
It could work except that it’s harder to say than [name]Susannah[/name], and nicknames are traditionally easier to say than the given name…
Maybe Zannah?
Sansa could work. [name]Ive[/name] always loved [name]Susannah[/name] nn [name]Annie[/name]
I like the above suggestion of Zannah as well
Sansa works… Reminds me of [name]Santa[/name] though (I have [name]Christmas[/name] on the brain lol)
There’s also [name]Sukey[/name], which I love as a nickname fo [name]Susannah[/name].
I also like previous posters’ suggestion of Zannah. That’s really cute. Susu is also a possibility.
[name]Sosie[/name]!
It’s a diminutive of [name]Susan[/name] according to nameberry. I love [name]Sosie[/name] so much I almost want to use it on its own.
OH! What about [name]Sunny[/name]? That would be a happy, upbeat nickname for [name]Susannah[/name]
San, Sanny or Sannah? Sass or Sassy?
[name]Sanna[/name], [name]Zuzu[/name], [name]Sasha[/name], [name]Sookie[/name], [name]Santi[/name], [name]Sun[/name],
What about [name]Lily[/name]? [name]Susanna[/name] means lily. I think [name]Sunny[/name] or [name]Annie[/name] would be SO CUTE. [name]Sosie[/name] is pretty cute too! 
I think Sansa, [name]Sookie[/name], and [name]Sosie[/name] would be great nn options for [name]Susannah[/name]. (Sansa is my favorite -> I can totally
see it being the name a little girl would accidentally give themselves when they can’t pronounce [name]Susannah[/name]. :))
[name]Love[/name] the name [name]Susannah[/name], I think I would ultimately end up calling her Suze, but I love the suggestion of Zannah!
I think Sansa could definitely work. I love the suggestions of [name]Annie[/name], [name]Sosie[/name], [name]Lily[/name], and [name]Zuzu[/name], too. There’s always the Dutch [name]Sanne[/name], too.
I really like [name]Sukey[/name], [name]Sunny[/name] & [name]Sosie[/name]. Thanks for the suggestions - [name]Susannah[/name] is definitely going on the list!
Yay! I love [name]Sosie[/name] and [name]Sukey[/name], though I like it spelled [name]Suki[/name] (I know a [name]Susannah[/name] who goes by [name]Suki[/name] and I like its minimal, Japanese look.)
My all-time favorite [name]Susannah[/name] nick would have to be [name]Zuzu[/name]. Makes me think of It’s a Wonderful Life.
[name]Sukey[/name]/[name]Suki[/name] is a nickname for [name]Susannah[/name], as well as [name]Sanna[/name] (I know a [name]Suzanne[/name] who went by [name]Zanna[/name]).
