Names for same-sex parents? - Parentberries

Been thinking a bit about this recently and I suppose now is as good a time as any to ask it. What are the best names, from experience or just your theoretical opinion, for same sex female parents? I called my own mother Mamá or Mamita a lot of the time, so I was thinking I could be one of those (most likely Mamá as I think Mamita is a bit long) and my other half could be just Mum (we’re English, so no Mom!) but I don’t know if those sound distinct enough (Mama has the emphasis on the second syllable), or if it would just be confusing when she calls for us.

Does anyone have any alternatives?
