Anyone happy to share their experience of preteens and tiredness? My 12-yr-old ds says he's sleepy all the time, dozing in quiet moments at school etc. I have an anxiety disorder, which means that I assume there's something seriously wrong (my mind always goes to cancer!) when my kids report relatively minor health troubles. I'm aware that I don't always see straight. Given that my kids won't be served by me overreacting, do you think this is par for the course when kids are approaching puberty, or should I take him to the doc?
