Aunt name

Ok, so right now the older kids call me Aunt Sarah. Which is ok, I guess. For the twins I've been saying Auntie Sarah, mostly to Abby, because she's the one who seems to like me more. Eli is just so nonchalant about everything. I really would like some kind of cute aunt name, but there's not that many options out there for "Sarah". Here's what I've come up with so far...

• Rahrah
• Sasa
• Essie
• Nana

So that's the best I could come up with after way too much surfing on the net. Opinions on these or suggestions for something else are greatly welcomed.
