Down???

Her new word is "down?" and she is constantly saying this. She is so quick to ask "down?" when she is getting her diaper changed or is in her stroller or carseat. When she wakes up from her nap I hear her in her crib yelling "down?". She is also repeating us like crazy. Everything that comes out of our mouths is repeated right back to us so we need to start watching our language in front of her these days.
