My 12 year old was a terrible sleeper in infancy and hugely clingy up to age 6. She later developed loades of sensory issues - wouldn't eat most foods, hated wearing shoes/ bathing etc.. For the past 5 years she has become increasingly argumentative and defiant. She screams at us mid discussion if she gets slightly frustrated. She is constantly rude/swears. She literally defies us in front of us and has no respect at all. I feel I am walking on egg shells scared to set her off. I think this might be adhd? Is this similar to anyone eles experience?
