Olive has started pretending.
For the most part, she pretends to be different animals. Cats, horses and lions are current faves.
The other morning, I went in to her room and was greeted by, "Roar. Lion. Meow. Cat."
Her horse act includes the requisite sound effects, and is accompanied by a 'gallop' that is super cute.

8/23/2011 This morning Olive woke up in a snake-y mood. As I changed her diaper, she repeated, "Sssss. Snake. Mamee. Sssss. Snake. Sssss." Thankfully for my diaper changing task, there was no associated wriggling.
