My T says that Winnicott defined it as like everytime a baby cried, that was a "rupture" between mother and child, that mother then repairs the problem, and in process of doing so, strengthens the bond between mother and child. So during a session, I could easily feel minorly disrupted several times, so I will assume you are asking, how many times did you almost quit this T but make it up? But my answer is still the same - 5+.
