Quack Quack or Quughughqugh?

Liam has a new duck sound. He has had fun lately discoving the new noises he can make with his mouth. He truely is a boy. It is amazing, I am learning that boys have a God given talent to make sound effects.  I think he must have heard Donold duck or something because he will be playing along and then out comes his duck noise. I tried to get his face while he does it. Sometimes he does it so long he makes him self cough. It makes me laugh, so I thought I would share...
