My 14 yo is not sleeping. And she's getting me up 2-3 times per night for reassurance. She goes to sleep ok but then wakes up and gets anxious. She's generally v mature so I've tried reasoning with her, and she understands but can't break the habit. I don't want to ignore her in the night. I used to get anxious too and I wouldn't have wanted to be left alone. But what else can I do? Is there anyone I can speak to for help?
