That is one of the first things that would be in the parenting book - don't ever smell what they want you to smell.
Last night in my semi-conscious medicated state Julia was sitting next to me on the bed, cuddling.
"Mom, smell this?" she said with a quizzical look on her face, holding out her hand in front of my face.
Not thinking twice in my dazed state, I smelled her hand.
It smelled terrible - terrible isn't even really the word.
Pulling my head back into the pillow as far away as I could from her hand, "What is that??"
"Oh, I farted on my hand."
