Dirty mouth?

You know when you don't hear your kid(s) there is something suspicious going on. I found Max and my purse on my bedroom floor. Smelling minty fresh. I had to pull the last piece out of his mouth, wrapper included. Looks like a he chewed each piece (maybe 6?) a little and put it back in the packaging. A couple minutes after he was caught, he was giggling and jumping on the couch and fell off. Hard! A couple minutes after that, he fell asleep in my arms. It's 7pm...keep your fingers crossed he stays that way!!!!
