Some parents may spank a child and others are offended by spanking, but a swat to the behind can prevent serious injury. My daughter was climbing up the steps to the second floor, on the wrong side of the banister, and received an immediate swat, resulting in no more dangerous step climbing.

I think that washing a kids' mouth out with soap is not the way to go, but using vinegar or raw onion is a pretty good start. Using Tabasco might work on some kids, but my son loves hot sauces and he would probably ask for more. Using hot sauce might appall some folks, but a drop of Tabasco is not going to kill the child. So you can see that there are many ways to address an issue that may strike you as "wrong" personally, but are not harmful to the child.
