What do you call your Dominican Mother-in-law?

I used to call my suegra Mam? (used to, because she passed away) and my suegro Pap?. I think this was my choice to call them what their own kids call them because they were both such respectable, commanding figures that to call them anything else would have seemed wrong to me. But no one said I should call them anything in particular - that was my choice. I wonder what I'll call my next in-laws...(Joking)

By contrast, my husband calls my parents by their first names. So I think it's a question of comfort, rather than custom.

My husband and I call his Dominican mother mami and my Canadian mother mom. His father is papa, mine is dad.

I call them suegra/o and if i am being smart i call them Mom and Dad in english !! They only speak spanish and I don't think they know what it means!

Many women call them Do?a followed by their name. Some would prefer to call them La difunta... _{^{ducks and run}}

Do?a

When I first got married, I tried my best to be respectful and polite (as I was raised to do), so I called my mother-in-law "Do?a Hilda." One day my wife took me aside and said that it would probably please her mother if I started calling her "Mam?" just as my wife did. So I tried it, and her face lit up so much that I call her that to this day. She and I get along extremely well, and she has said many times that I am the son she never had...
[An aside: my wife's maternal aunt is also her madrina. After seeing my wife greet her several times with "Bencion, madrina," ("besando la mano") and receiving the blessing, I tried calling her madrina and seeking the blessing. She loved it. And she still eats it up when I enter a room full of family and she's about the first person I greet, always seeking the blessing first before conversing.]
My wife's father was killed when she was only 2, so I never had a chance to test "Pap?" on him. By all accounts her was a serious and imposing fellow, so I probably would have been hesitant to call him anything but "Don Daimiro" unless he himself instructed me to do so.
My family is very relaxed and informal about such things and they adore my wife, so she very quickly fell into calling them "Dad" and "Mom."
Best Regards,

I always used "don Fulano" with my suegro

But my mother in law was Mama Yuya, for me and the whole freakin' town! A great woman, eaten away by Altzheimer's, all too soon...Christmas has never been the same...

I call my mom-in-law and father-in-law mama y papa. The same with Aunties and Uncles, it's Tia y Tio. I don't think anything could make them happier.
