PLEASE!! (Used at appropriate times, too - she's already excellent at manipulation.)
There she is! (When she pops out from hiding, she copies the phrase we use.)
Airplane! (Whenever she hears an airplane, she gets really excited about trying to find it in the sky, and she is usually the one that ends up pointing it out to me. Also, she says this pretty much all day long when she wants to see an airplane, so sometimes we take airplane-watching expeditions outside.)
When she wants to leave a place, she starts telling everyone goodbye.
She likes to sing "This Old Man", but she just sings that first phrase over...and over...and over...
And the fun goes on and on. We just thought we'd share these few tidbits with you.
