Eva softly sauntered downstairs after her nap and carefully wiped the sleep from her eyes.

"Mom, do you know about breathing?"  she asked.

"Yes I do"

"Ok. Can you tell me all about it please?"

"Sure" I said as she crawled up beside me on the couch and I explained to my 3-year old how carbon dioxide and oxygen worked.

"Thanks Mom" she said when I finished.

"No problem."
