(4) Massaging the “V” between the thumb and pointer finger
Cradle their hand with one of your hands while placing the thumb of your other hand (of the hand that’s free) in the fleshy part of their hand between their thumb and pointer finger. Firmly (make sure you ask it’s not too hard) squeeze your thumb down on their area while grasping from below with your other fingers. Rub in a circular pattern for about ~30 seconds.
