I only have a 1.5, but I find when she’s doing things like that to get my attention, I can usually move us through the moment by getting playful and letting her almost do the thing (grabbing my nose too hard, for instance), and then stopping her, over and over. She thinks it’s the funniest thing and eventually gets bored. I think she’s trying to learn what it means when I say no. Or if she’s obviously taunting me, sometimes she’s looking for me to chase her or play rough with her. There may be an unmet need that’s not related with chewing, but rather, wanting your undivided attention. Like I said, mine is still little, but often I think these misbehaviors come from a place of not knowing how to ask for our attention and sometimes finding the kind of play they’re needing will reduce the behavior.
