My Kid has Been Brainwashed

Lizzie has developed a sudden intense fear of bees. We have been trying to convince Addie to help her be brave which is hard because Addie started this fear of bees. We were outside yesterday and Lizzie started crying and yelling, "bee, bee." Nick told Addie to run down and help her to be brave. Addie ran down to Lizzie and said, "Lizzie, Livestrong, Livestrong."
Wow. I don't know where she comes from.
