Bullying tips:
What is Bullying? (From the University of Colorado at Boulder, Center for the Study and Prevention of Violence, Safe School Fact Sheets, Bullying Prevention: An Overview of Bullying)

- Take the situation seriously. Don’t assume that it is ok or that everyone gets bullied.
- Focus on your child. Listen to him/her, don’t blame him/her, empathize, ask questions to find out details of the situation (Who? What? How often? Where?), do NOT suggest that your child “fight back,” and don’t let your emotions take over during the next steps.
- Contact the school (through the social worker, teacher, principal, guidance counselor) and voice your concerns (don’t let emotions take over). Make sure the school takes the situation seriously too.
- Work with the school. Let the school know you want to work together with them.
- Have school personnel attempt to set up a meeting between you and the bully’s caregiver(s). Don’t contact the bully’s caregiver(s) yourself.
- Guarantee that your child is protected at school. Communicate with the school and ensure that teachers/administrators are aware of the situation and are closely monitoring it.
- Encourage your child to meet friendly classmates and to spend time with them outside of school.
- Help your child meet friends in different environments (clubs, sports, volunteering)
Signs that your child is a bully (from US Dept. or Health and Human Services, Substance Abuse and Mental Health Services Admin, National Mental Health Information Center, www.samhsa.gov

Discipline Information: 12 – 15 years
(revised by Kimberly Greder, Iowa State University, University Extension, revised April 2003)
Discipline at this age is more about building a good relationship with your child (ren)
- Listen to your child and help him/her acknowledge feelings. For example, if your child says “I didn’t get invited to a classmate’s birthday party,” you could say “It sounds like you are feeling left out.”
- Remember that your child is changing physically, socially, and emotionally. It is normal for him/her to want to be independent, spend more time with friends, and challenge your authority.
- Praise good behavior! Your child will learn to repeat good behaviors if they are encouraged and/or if privileges are given in response. Be specific with your praise (“Thank you for cleaning up your room. It looks great.”)
- Give rewards for good behavior. Rewards don’t have to be “things.” Extra privileges (staying up later, inviting a friend over) and spending one on one time with your child are excellent rewards.
- Plan and do things together as a family. Let your child help plan family activities.
- Use reflective listening. When you are talking with your child, listen to him/her and summarize what he/she is saying. This will let your child know you understand him/her and gives him/her a chance to clarify if you aren’t “getting it”.
- Make sure to spend one on one time with your child.
- Take advantage of time in the car/on the bus together to talk with your child. For example, you can ask about his/her day (what will you be doing today? What did you do today?)
- Let your child know what your values are. Let them know what you think is important and find out what they think is important.
- Have regular family meetings.
Tips for dealing with problems that will occur
- Express your own feelings about the situation by using “I” statements. For example, “I get worried when you come home late and don’t call because I don’t know where you are” instead of “You shouldn’t be coming home late without calling.”
- Let your child experience natural consequences. For example, if your child forgets his/her lunch at home; allow him/her to feel how hungry he/she gets. Don’t keep lecturing your child; let him/her remember on his/her own.
- Give consequences that match the problem behavior. They should relate to the problem and be reasonable. Let your child know what these consequences will be. For example, if your child uses too many cell phone minutes one month, take away their phone for a few days.
- Work with your child to figure out a solution. Listen to his or her ideas and give ideas of your own. Come up with a solution you can both live with.
- Remember to follow through and stick to your word. If you or your children have agreed to something, stick to the agreement.
- Don’t discipline your child when you are angry or upset. Wait until you are calm.
- Don’t discipline your child when he or she is angry or upset. Wait until they are calm.
- Give respect to get respect.
Parenting Mistakes
(by Mary Casey-Goldstein, Kevin Haggerty, and Richard Catalano (2002). “Raising Healthy Children Navigating Independence Booster Session.” Funded by the National Institute on Drug Abuse)
- Talking too much. Do you get tired of hearing yourself lecture your child? If yes, chances are you are talking too much and not listening enough.
- Not developing along with our child. Parents can’t use the same techniques when their child is 10 as they did when their child was 5.
- Focusing on negative behaviors and paying attention to your child when they do something you don’t approve of. “You raise what you praise.” If you focus on the bad behaviors, those are what you will see.
- Telling children what they shouldn’t do instead of what they should do. Give your child examples of behaviors that you want them to repeat.
- Reacting to children only after they have made a mistake. Parents need to set up rules for their children before problems occur, not in response to problems that have already occurred.
- Forgetting to have fun together.
