Hiccups are caused by
contraction of your baby's diaphragm, which is the muscle below her
rib cage that controls her breathing, accompanied by closure
of the vocal cords.
To unite prana and apana, we would focus on the SYMBOLIC downward movement
of the breath on the inhalation (nose — throat — chest — belly), facilitated by intentional muscular
contraction, and SYMBOLIC upward movement
of the breath on the exhalation (using progressive abdominal
contraction from the pubic bone toward the navel and then compressing the
rib cage).
