Both people who wet the bed after age 5, as well as aging people (usually women) with urinary incontinence issues have a reflex that’s useful in utero and during birth, but should not be in use at other times of our lives!  It also contributes to hypersensitive hearing, difficulties paying attention to things heard, as well as hyperactivity!  This responds nicely to movement therapy, particularly lots of games.  People are delighted to find that other things, like focus and attention, also improve with exercises.
