this one, when given the option of either having a time out or a spanking as a punishment for biting her sister and being rude, will stand there, hands on hips, think about it and reply with "how hard will you spank me'?. in her mind a spanking is better because it's over and done with and she can get on with her business.
this is what i deal with.
and yes, i'm one of those parents that disciplines her kids. there is nothing more gross than seeing a child who never gets disciplined, turn into a bratty, privileged older child.
