Yesterday, I swore I smelled sour milk in our living room. Joe didn’t smell anything, so I figured I was just imagining things.

But, when we got home from work, Joe said he could smell it, too. We moved the couch and pulled out all of Lucy’s toys. No sippy cup there. We couldn’t figure out where the smell was coming from.

Then, as I was sitting on the couch watching TV, Lucy went over to her kitchen, opened one of the doors, pulled out a sippy cup and brought it to me. And old sippy cup. And when I say old, I mean that when she spilled it on my arm, the milk was as clear as water.

Mystery solved, and now Lucy is down one sippy cup. Now, if we can just get rid of this smell!
