My daughter is 12 and was diagnosed a few years ago. Recently she started falling off in school again, bad grades and not turning in homework. I am not sure if the hormonal shift of the tween years has effected her ADHD at all. She takes medication for her anxiety but not currently for ADHD. I got stuck in a cycle of blaming the diagnosis when things go bad. But I need to hold her accountable also. However last night I took everything away from her phone, kindle, her after school outings with friends and she just doesn't care. She had failed a test and her teacher was kind enough to give her an opportunity for extra credit by completing a brief project during lunch, she chose not to show up for it. In addition to not handing in the homework she lied to me about doing in the same class. I had to punish her but is it really effective when she doesn't care about it. Anyone else experience this? Any things that worked with your kids?
