What Should Baby Call Two Mommies? (Need Advice!)

I didn’t really know how to word the title, but my daughter will be growing up with two mommies, and I’m not sure how to refer to ourselves so she learns who each of us are without being confused (when she’s really young). Because if we only say “mommy” while referring to either one of us, she won’t know which one we’re talking about. Any advice? I was thinking of one of us being mommy and one being mama but I feel like that’s too similar? I’m kinda stuck!
