I suppose all parents/caregivers may feel this way from time to time, but when a child does not listen to you or you have had a "parenting fail" so to speak, how do you deal with this?
A four year old developed a habit (a long time ago) of climbing on top of cars.
One family member has a habit of flipping the f--- out! when the child climbs on top of a car.
As a sort of "overcorrection" to this, I calmly ask the child to not climb on top of the car, and this used to work.
However, the particular incident I am citing had this child climbing on top of the car, and me not doing anything about it, except calmly asking the child to stop climbing on the car. I'm not sure why I wasn't doing anything else about it, but I wasn't. Finally I warned the child that the glass on the windshield could break, and he would be injured if it did. So the child proceeded to stomp on the windshield, at which point I took him off.
Of course, this wasn't without consequence, and the windshield had a hairline crack after that.
I was really mad. See my answer for my resolution.
