Lately whenever E is trying to get her way on something, usually another story before bed time, or stalling when it comes to dinner, she says "a couple minutes." She puts her index finger up in front of her mouth, almost like a sushing motion, and says it. I find this one very funny because she has no actual idea what a couple of minutes actually is, or how long it might be.
We've also been practicing manners with E, and the concept that seems to have stuck is "excuse me." She uses it all the time, just no to people, the other day she was trying to walk past a dog and said "excuse me puppy" and got upset when he didn't move. Tonight, she wanted one of her toys to move and said "excuse me Zoey."
