My advice for the high school years.

1. Stay involved in your teen's school activities, but allow more independence.
2. Know their schedule and teachers.
3. Be aware of power struggles with the teenager guys. Freshmen guys may feel much more anxious about this. Notice changes in your son's mood.
4. Don't let the usual moodiness keep you from asking them questions. My motto, I had rather ask out of concern and be wrong than avoid and miss something.
5. Girls are more likely to tell you the social stuff but with guys you must look for the hidden messages they may be sending you, like, "I hate my math class." Ask why and listen, don't interrupt.
6. Girls face bullying as well. She may tell you specifics about certain people and how they treat her. Listen and pray for wisdom.
7. I always ask if there is something they need me to do to help. It helps them feel more in control. Of course if it involves a safety issue, NEVER HESITATE TO STEP IN.
8. Freshmen girls face attention from the older guys . I was specific with my daughter about this and older guys. I gave her facts, information and motherly concern. Keep it objective not subjective. And you better cover this subject before it comes up.
9. Never assume a friend's home is safe for a party or sleep over. This is the ripe time to start drinking, experimenting and such. Many homes allow social drinking. Alcohol that isn't being accounted for responsibly is a tickling bomb to teenagers. Never assume a sleep over is one sex. Co-ed sleep overs happen every weekend. ASK.
10. High school is a great time. When parenting changes and grows along with our teenagers, show your love and concern first. Boundaries say I CARE ABOUT WHAT YOU DO. The only difference in high school is we parents need to increase our communication skills, listening skills, and hit the floor running with God's grace and wisdom for each new and exciting stage of our teenager's life.
