The reverse peek-a-boo

Today, Emma was playing with daddy by moving her head back and forth behind his pillowcase and then a bucket on the kitchen floor playing peek-a-boo with him.  She would hide her face and then move so she could see me and I would say peek-a-boo and she would giggle and hide again.  Before, it has been me hiding and coming into view.   She is also much more talkative all of a sudden.  Maybe words are on the way?
