Picture the display at the front of most Old Navy stores: A family of mannequins, all decked out in the latest styles from head to toe. Complete with the family dog, of course!
Flash through these freeze frames with me.
I am at the check out, and Phoenix is walking around the mannequin family, marveling at them.
Frame 1: I look over, and he is riding on the family dog.
Frame 2: I glance back again, and he standing with the mommy mannequin, holding her hand and sucking his thumb. Just like in this post - only with a substitute mannequin-digit!
Frame 3: One more glance and there he is again, this time holding the daddy mannequin's toe, still sucking his other thumb.
