"Where's Daddy?", "Where's the toy or ball", "Wanna see?" (she knows this means I will pick her up to look out the door!)
The one we have the Most Fun with is "I'm gonna go HIDE!"
"you wanna find me?" My Husband & I take turns hiding like kids, then she takes off to all the usual places as I proceed to say "where is he?" Of course, it's Hilarious to watch & when she finds him, she gets lots of Laughter/Praise!
