We are at our wits end in dealing with our 4 year old's behavior.
I don't know if this work on a Kinder but my gf who was having trouble with her 3rd grader started having him work for privileges.
You may want to have him evaluated by a developmental pediatrician for developmental delays. Two of my kids were diagnosed with a high functioning form of autism (Asperger's Syndrome) when they were 8 & 12yo. Because they are so high functioning and very intelligent, it took awhile for anyone to realize that there was a diagnosable problem. Although my children's physical development, language skills, and academic abilities weren't delayed, their social, emotional, and sensory skills are very delayed.
I don't know that your ds has autism, but some things that are potential flags are things like:
* early and advanced speech* being able to repeat back movies verbatim, esp when he hasn't seen them in months* inappropriate responses to emotions in others* problems in school (can be due to various reasons, such as sensory overload)* typical disciplinary measures don't work because they aren't acting out for typical reasons
Like I said, your ds may not have autism. Obviously I'm a bit more tuned into autism because of my own kids, but it's been a startling discovery for me to realize how many kids have autism (1 in 150)! Your ds may have a different diagnosis or just be a spirited child. Any way about it, I'd recommend an evaluation by a developmental pediatrician (or neuropsychologist). If there IS a problem, the earlier you start interventions, the better. If there's no problem, perhaps the doc can give you ideas on better ways to work with a spirited child.
I think the previous posters have given you some great advice and I really don't have anything to add to it. I just wanted to say I hope you can find a solution to his behavior and please keep us updated.
