And along with their own laundry, they brought two Christmas dresses for Birdie & Cricket with a note. Birdie is going to see Santa today but Cricket is sitting this year out due to the fact that if she even SEES the Santa house at the mall, she recoils in terror and starts screaming. And as much as I know some people would say, 'just throw her on his lap and take the picture!' I won't do that to her. She is genuinely afraid and that's ok. We talk about it and she says 'Maybe next year.' Until then, we have the Elves!"
