You don’t communicate through your feet

DD2, my youngest has this habit of using her feet for expressive communication, she’s elevated fidgeting to a new level. It’s not some form of contemporary dance, she’ll lie on her back and tap me with her toes, or point at something going, mmm mm mmmmm MMMMMMMMMM. Argh, it’s so bloody annoying. She’s so fidgety, I don’t know why, I don’t understand what has created that behaviour.
