My Baby Nephew's Skyler's Funny Laugh

This was my sister's, @shellany's baby boy's, Iphone video about five years ago. Baby Skyler was about six month's old or more when he would laugh and shriek so hard at the sound of "Quack, quack!!!".

My mother would have to hold him carefully while he would struggle with his seemingly uncontrollable laughter. It was a pleasant reminder of the good old times.
