This is probably completely geeky that I even remember this, but have any of you read the "Mary Poppins" books? Yes, there's more than one. Actually, four books in all.
Anyway, in one of them, Jane and Michael Banks have twins introduced as additional younger siblings. I remember they have their "twin conversations" very early on in the book. P.L. Travers says, at that point in their lives, they can speak to all animals and everything else alive. And to each other. But not to other human beings. So they talk to birds and cats and plants, etc. They can all communicate together. And it's only as they start to learn English that they forget how to talk in this special language of "nature."
I found it to be very bittersweet and moving. And I've never forgotten it, even though I read those books as a kid. I love the idea of this special, secret language that only babies know. Especially twins, who can share it with each other and all other creatures. And it's sad to watch them outgrow it and lose that magic ability.
