Ok, so Kason and Cohen are currently LOVING The Wiggles. As in, they would watch it all day, everyday if they possibly could. In their favourite DVD, there is a bit where a little girl giggles with her hand over her mouth. This is now how Cohen and Kason giggle.
In this picture, they are being very cheeky and opening and closing the DVD tray. Everytime it opens they giggle this VERY cheeky giggle with their hands over their mouths, looking at each other. I love that they love having fun together :-D
