What should I do? I have custody of my child 50% of the time, and I've observed her frequently playing with her hair. She rolls it tightly with her fingers. Typically, I wouldn't be concerned, considering kids will be kids and fiddle around. However, her mother struggles with Trichotillomania (hair pulling disorder), and I'm deeply worried that my child might adopt similar behaviour over time, even though it doesn't seem like she's actively pulling her hair at the moment. Any advice is gratefully received.
