I’ve heard that boys typically take longer to “care” about hygiene and such. Boring tasks like this are even harder for those with ADHD. My son is 16 and I still remind him to shower, brush teeth, etc. Kids with ADHD are developmentally 2-3 years delayed, so that has something to do with it as well. Routine can really help so these things become habits they don’t even think about. For example, brush your teeth first thing when you get out of bed. Shower after dinner every night…
