Caz? Similar but more masculine I agree that Perry would be a nice option too
Cas
Casp, but I’d also love Cassie as the nickname haha
Perry Caspie Cappy Casey Casp Sper Cap Paz 💙
We have a lot of non related nicknames for our kids like bug, nugget, gamin’ Amon, bubba, angel. You could do initials for him as well or like my sister does she insists everyone use the full name. She’s pretty aggressive about it, which is fine but yeah some people really don’t want you to shorten the name.
Cas will definitely happen at least at some point .
Casy, perry, cap
