The Boy has pretty much been obsessed with a limited number of "fairly typical" things...helicopters, Cars, water, pin wheels, etc. It gets on my nerves, but it doesn't rule our lives...e.g., he has helicopter toys, but he isn't allowed to only play with them. We don't feed the obsession, but so far haven't "banned" anything (we did have to remove helicopters at one point because he was just "stuck"). This morning, for whatever reason, The Boy woke up obsessed with hair. I have absolutely no idea what it's about, but it's incredibly strange. He found a barbie with long hair, and has been wandering around talking about her hair, about how he is going to have long hair, about how his hair is soft, etc. Beyond weird, and I just can't be that parent who says "go for it" and buys the kid a wig. Right now, we're ignoring it completely to see if it goes away on its own but ohhhh how I hope he comes up with something new fast. For those of you with kids with Obsessive Compulsive Disorder (OCD)/Autism Spectrum Disorders (ASD)/etc...what has been your kiddos strangest obsession? Also: I should probably post this as a separate thread, but...for those of your children with mental illness vs Autism Spectrum Disorders (ASD)/Obsessive Compulsive Disorder (OCD)/ADHD...can they "turn it off" for periods of time? We still aren't sure what The Boy's actual diagnosis is, and I'm just curious. He can (after days/weeks of more typical behavior) wake up completely "crazy" in the morning with high pressurized speech, completely unfocused and unable to answer questions, only focused on his obsessions and saying things that don't make sense. We do "summer homeschool," and when I say it's time to work, he can turn off the "crazy" for a couple of hours and complete the tasks. I've had kids with both Autism Spectrum Disorders (ASD) and MI diagnosis at work and none of them have been able to "turn it off."
