It took 8 months, but Cardi B and Offsetare finally revealing their baby boy’s name and showing him off to the world — so get ready to meet Wave Set Cephus!!!

The proud parents both posted pics Thursday of their little bundle of joy, already iced out in Cuban link chains … with Offset revealing the unique name in the caption.

Cardi posted a different shot of her son … wearing a baby blue puffy jacket, and you can see Wave Set has a huge iced-out pendant hanging off those Cuban links.

Don’t worry … he’ll grow into it.
