I think it comes mostly naturally. Babies have no guile or instinct to deceive; they literally can't even conceive of doing so because their worldview just isn't developed enough. So when your baby cries, you can have absolute faith that it's because there's some problem that needs solving or need that is unmet, and then you can go and solve the problem, fill the need, and the baby is happy. And when the baby's happy, you have absolute faith that it's because you were there doing the thing. There's no pretense to the relationship at all, and it's a sort of unusual honesty that can be really hard to find in relationships where both parties understand basic facts like "there is a world of people outside myself" and "people don't have special insight into my interior being and I can give them information that doesn't fully reflect the state of the world". So that kind of honest exchange does a lot to foster love and adoration from you to the child, and the fact that you're there providing food, shelter, comfort et all to the baby fosters love and adoration from them to you. My kid is just under 18 months old now. He's old enough to have distinct ideas about what he wants to do, and when he wants to do it, and he's old enough to understand that not getting to do the thing that he wants is really upsetting, so he cries. That's hard sometimes. But if I'm relaxing on the couch and he brings a book over to me, I can know with absolute faith that it's because right now, what he wants more than anything in the world is to sit in my lap and have me read a book to him, and that feels amazing. When he goes and hides behind the kitchen island and then jumps out, it's because the thing he wants to do more than anything else is play peekaboo with me, and that feels amazing too.
