My daughter, raised by me primarily (had a job working 24 on/48off) understood that swift punishment happened at the time of the offense, and sometimes, that meant physical. She is incredibly well behaved for me and ANY OTHER MEN. It's weird, but my X (her mother) refused to discipline her, now she doesn't RESPECT WOMEN. She is incredibly disrespectfull of them. therapist says she doesn't respect them or fear consequenses from them. Now, my son, raised primarily by my X (I was at war in the Gulf) Only listens to women, men he doesn't understand a deep tone (he is rattled when any kind of male authoritative voice is used), or male mentality. She never disciplined him, gave him whatever he wanted and now if it isn't what he wants, he won't do it. To the depravation of his education and physical/mental development. He is smart as all get out, but doesn't learn it if he doesn't want it. He was one who definetly needed to learn direct consequences early. And the components of my family will pay for it, but mostly him later on in life.
