One of Kate's new tricks is "answering" the phone. If you say, "Ring, ring" her response is to put whatever she's holding in her right hand to her ear. In this case, it was nothing. She answered the phone with her hand. She can also verbalize that a puppy says, "Woof woof."
Hannah is my peek-a-boo queen. She has learned how to do various kinds of peek-a-boo. Her latest is covering her eyes with her hands, demonstrated in this picture. All you have to say is, "Where's Hannah?" and she covers her eyes. Sometimes she cheats a little and peeks through her fingers.
