Huh?

Ava's Quote of the day:

"Sometimes when i go to bed at night, the bubbles come!"

This is what Ava said AFTER i had put her to bed. she came running screaming to the kitchen. I did my magic mommy thing and then put her back to bed. She said the quote so matter-of-factly.

Does anyone want to guess what she's talking about?

It's a hard one, but i wanted to see if someone could figure it out! :)
