Mittens. Are you??

The other day Nora and I were getting ready to leave for the St. Patricks Day parade. It was COLD outside so I told her we had to find her mittens before we could leave. Her response to this statement?  "Mittens. Are you? Mittens"? As though the mittens were going to come jumping out of the bag and right onto her hands. Since then everything is "Are you". Dadda are you? Mamma are you? Petey, Casey are you? This afternoon after I told her we had no cookies she said "cookies are you"? Oh this silly girl. I LOVE listening to her learn to talk! It seems so unreal that she really is old enough to be saying so much!
