If for some reason you can't view the clip, the technique is for the dad to stand behind the very small child who's wearing a winter coat and boots, with said dad using his own shoes to squeeze in on the kid's boots from both sides, and then by firmly grasping the kid by the back of the coat lift said kid out of the boots. As a bonus this seems to amuse the kid.
