How to tell family I’m pregnant 2 months postpartum?

I’m really nervous idk how to tell family me & my husband we’re sure that we were done at 2 plus 3 of my siblings just had babies as well….

I have no idea how to tell them me & my husband have come to terms & are excited but I think part of my family will be upset & definitely surprised….

I wanna do something fun/ funny to make it kind of exciting.

Any ideas??
