"Stella night night"

Stella seems to have suddenly figured everything out. It's as if a light bulb went on over her head, as Jen says. She just seems to understand what we're saying to her. For example, tonight we were playing down in the basement as we do every night before bed. At 7:15, we usually start getting her upstairs to get her ready for bed. Tonight, I looked at her and said "Stella, night night". She instantly stopped what she was doing and made a bee line straight for the stairs . Amazing! We've probably only said "Stella night night" to her a few times but she understands now exactly what it means.
