Nicknames For Sullivan

My first son is Jameson and we call him Jameo at home. We introduce him as Jameson because we obviously love the name and it is his birth name.

I am leaning towards Sullivan for our second and would love a playful nickname to use at home. Ivan, Sully, and Van haven’t quite grown on me yet.

I’m curious if there are any other Sullivan mommas out there that have alternate nicknames for their little guys or if anyone has any suggestions.
