You may never get certainty, and that can be uncomfortable. Instead of looking for proof, pay attention to changes. Withdrawal, irritability, sudden secrecy around devices, sleep disruption, school avoidance, or shifts in friendships can all be signs that something is weighing on them.
These signs don’t automatically mean harm, but they do mean your child needs connection. Rather than interrogating, try gentle check-ins over time. “I’ve noticed you seem quieter lately. I’m here if something’s bothering you.” Consistent presence is more effective than one intense conversation.
