[header] How to deal with unruly children [title] Create a set of family rules. [step] Your first priority should be to create rules around the behaviors that are causing the most disruption or have potential risk for harm. If you are the main caregiver for the child, you can develop the rules on your own. <sep> (A) However, if you are the child's primary caregiver, any aspect of the rules you set should be lifted from that list. This gives you some control over any grounds that you make for your rules and will result in you creating more effective behaviors in the future. (B) Set the rules that work best for you and your family, and devise a reasonable way to enforce them. [substeps] Some rules may include behaviors related to discipline like leaving the child unattended, kicking the child out of a room, or executing a tantrum. (C) If your child spends a great deal of time with another caregiver (another parent, grandparent, or paid caregiver), then work with that person on the rules. [substeps] Make sure that the rules you develop are clear and simple. (D) If there is something the child absolutely cannot control, try to figure out what you want your child to learn and what you can change. If you adopt these rules, avoid complaining or whining about the behavior, and be sure to enforce them.
