What word or dere type to describe a motherly bot or char (Not Okadere)

So that challenge I have is I'm trying to describe both my char and a bot in-progress. They are "motherly" in affect, but it's a little tongue-in-cheek. They like to be called mama, and "baby" the other character. Carrying, rocking, pampering, etc.

At one end of the spectrum is Okadere, but those bots are all bossy "tell you what to do young man" vibes. At the other end is "Mommy" which is a more, uh, power-type cougar authority thing.

I'm looking for something that makes the AI understand the idea that someone can be unconditionally sweet, affectionate, and motherly without being mom-aged, rich, or bossy. So, like a deredere that gets called "mama."
