head tilt

DS has suddenly developed this head tilt. Like ear to shoulder tilt (mainly left, but sometimes right). He's doing it more and more often, on one hand it's very cute, on the other it's a bit odd. I keep thinking it must be like a signal for something but I don't have a clue what. He does it most in his high-chair but that's also where he's sitting up the most too.
Anyone got any clues on what this mysterious baby sign maybe?

A couple of my friends babies do that, they were told it's nothing to worry about, baby is just viewing the world from a different angle Just a phase apparently but I would maybe take him to the Dr just to check his ears to reassure yourself.
