Keep Turning it up!

I'm kinda busy right now catching up the time before it hits to 10 pm but how can I make my work faster hence my daughter is keeping the tv turning up? Ugh! I tried to have her use a headphone but it is just working for few minutes after that she gets tired of it and took off hehe! She is pretty smart little girl because I believe she knew that it is one of my trick to not bother me while I'm working something here online.
