How do I control my 4 year old bad behavior?

They recruited 80 fathers and mothers, each parent with at least one child under age 18. The parents were about 37 years old on average, and the kids were about eight. Half the parents were primed to focus on the financial costs of parenting. They read a government document estimating that the costs of raising a child to age 18 exceed $190,000. The other parents got this information as well, but they also read about the financial benefits of parenting — that is, the fact that adult children often provide financial and practical support to aging parents. The idea was that some of the parents would be mentally calculating the out-of-pocket costs of having kids, while others would be left thinking of childrenas a mixed blessing, at least financially.
