Kay, I'm gonna put this simply: We're all attached to something. No matter if you're a depressed, isolated cold-stare anime protagonist or happy-go-lucky maniac, we've all been attached at some point in our lives. And that starts at birth.
We've all been there. The birth of a child! What a miracle!... Sure. You're staring down at a lump of baby and wondering, wow, this dude sucks. Unless you're one of those people who likes babies. Um, whatever floats your boat.
But these little ... bundles of joy lead interactions, apparently. According to some old dude, the 'adult' responds to the behaviour of some baby. From day one, their plans to dominate not only infant-caregiver interaction but at large the entire world is made clear, and I- ahem, WE are the only ones who can tell... the rest call us crazy. We'll see who's crazy.
The word 'reciprocal' (Reciprocity) means two-way. Have you ever had an unrequited crush? One that didn't reciprocate your feelings? Couldn't be a healthy caregiver and their demonspawn. They both take part in the interaction, and therefore respond to each other. Ever had a little tyke grin at you on the bus? Their caregiver probably smiled back a whole lot. They expect one back.
