Written in Partnership with In the City Camps | The number of tweens with attention-deficit hyperactivity disorder (ADHD) is increasing, but sadly, a growing number of preteens are rebelling against treatment. According to ADDitude magazine, tweens tend to stop taking their ADHD medication. Peer pressure is a big factor, but refusing to take medications may also be another way for them to assert their independence. Parents and other caregivers can help their tweens feel less stigmatized by showing them ways to take their pills in a less obvious manner or in private. If your preteen is going to a sleepover, for example, speak to at least one of the adult chaperones beforehand.
