@nobullyplz YES. It is THAT important to her. This is what mothers are, even if it's a basic, super simple thing, her instincts tell her to make sure she's 100% accurate and perfect at doing it because her baby is the focal point of the universe.
It's hard for dudes to accurately understand the gravity that a baby holds. It's the absolute center of life now, anything that has to do with its life and comfort is job #1, deserving of all her efforts no matter how simple and mundane. Her instincts push her in ways that guys can't quite understand. Sure, we get horniness as an instinct, fighting, struggling, but parental instincts are far and away so much stronger than anything we feel.
She's a woman, she needs to feel like the tribe approves of her, that she has their approval and protection as a vulnerable mother. She wants an expert to tell her, she NEEDS that thirst for community to be sated by having a living older woman tell her to her face and give her verbal feedback that she's able to feed her baby well.
Boys don't have those same inclinations for community, so we're obviously gonna say "jeez, dummy, just look it up and read the text on the page" but that doesn't fulfill her needs, because it's not just about obtaining the information.
