Toddler = Peeves?

Toddler is like poltergeist, is this normal? He is generally such a sweetie but frequently stops, looks us in the eye, grins and then does XYZ naughty thing, all while grinning and never breaking eye contact. Ie, pushes everything off coffee table, or slowly dumps box of crackers on floor, or stuffs whole cookie in mouth at once, or sticks finger up MY nose (all of these things are explicit no-nos in our house). Every time he does whatever bad behavior in slow-mo, while looking us in the eye, and grinning with glee.I know boundary-testing is 100% normal and healthy but the grinning and eye contact is throwing us off! I feel like we're living with Peeves the Poltergeist sometimes.Anyone else? via /r/Parenting http://ift.tt/2kmUcDx
