> The fact that suckling is a hardwired reflex is what makes using the nipple intuitive. You use it by doing the same thing you think you should do.

In this case it gets used automatically without choice or thought. Anything shoved into a baby's mouth triggers it. It's not intuition, just reflex. Intuition implies understanding.

It's the difference between "I know that what this is for and how to use it" vs "I have no idea what this is and I have no control over doing it, this is just something that is happening to me"

No, if anything it's the opposite. If you understand something, you'll find it easy to use. Intuition is what you rely on in the absence of understanding.

I'd say intuition is understanding in the absence of instruction or prior experience. Something intuitive should be something you find easy to use.
