Do you have someone who can help you burrito?
I have a super squirmy chin...who also knows exactly when/how to bite and slowly apply pressure. What I usually do is start off with a towel (not a normal shower towel, but one you would use for your hair thats about 1.5 ft by 3ft) that is folded in half. I put it against my chest and pick Gizmo up with my hand against his chest. I hold him against my chest with his back on the towel and usually the other person who is with me does the initial wrap around the front of his body. Once I have that done, I can rotate him and keep wrapping him myself.
It doesn't always work...and don't try to sneak attack them and do it too quickly. If your chin is a biter, wear some gloves lol. And make sure the feets and hands are wrapped, any inch of wiggle room gives them an out.
