Hi Brooke, I am sorry to hear you are having so much trouble with Mocha. Diesel used to be the same way, he chewed the cord to my laptop, the charger for my phone, and started pulling the wall paper off of one of my walls. I was so upset, especially about my laptop cord. I have now been using a water bottle with a few pennies in it. I started using it for Diesel's barking and sometimes use it for other disciplinary reasons. It works great. I have also found that a firm NO also works. Make sure that your baby has plenty to do and you should see a decrease in negative behavior. I hope this helps.
