I have figured out a solution for Connor playing on my mouse. I let him chew on my fingers but when I need him to click on something I say "Click" and he bites down on the mouse thus clicking on what I needed. Now this is not a full proof system but it is amusing.
I have no idea where Connor picked up this new habit buts its pretty funny. He has started smacking his "lips" and making slurping sounds with his tongue. Its pretty funny to hear him doing it when he eats. Little piggie haha. Could he have picked up the habit when I tried to get Blu to eat spinach? I did the thing where I acted like I enjoyed it and he must have learned to make the noise there.
If you made those noises then, it is possible for him to have learned it at that time. It is pretty amazing at how few times they have to hear something to repeat it, sometimes only once or twice.
