negotiating

It is frustrating in the extreme, the amount of negotiating that goes on with a three/four year old. I can see why it's necessary, as the alternative is smacking or sending him to his room/timeout. However... the time and patience and effort required (of two exhausted parents) is enough to drive me into the wilderness screaming, never to return. I feel like Zack "gets it" some of the time, so you can appeal to his rationality, but other times you're offering a number of alternatives, a number of carrots and sticks, consequences are carefully weighed up, end results are presented as clearly as possible. And yet, you're still getting the whinging, whining three year old who is just being contrarian for the sake of it. After 45 minutes of ruining everyone's day...
Yup, then it's time for a smack
