A sensory diet may help, and according to our biomed dr. hyperactivity can be a symptom of systemic yeast infection. http://www.tacanow.org/family-resources/what-is...

I haven't seen any improvement in my DD's hyperactivity since she started anti-yeast treatment with Nystatin but it did help quite a bit with potty-training, so I am glad we tried it. Another thing we will be trying at some point per our biomed dr. is a low-phenol diet. http://www.tacanow.org/family-resources/phenols...

It might be hard on him transitioning from one activity to a different activity/location and he's showing you this by pulling your hair and throwing tantrums. It's really helped my son when we give a warning such as "last minute" or if it's a game tell him that he has "2 more goes" until it's over. Give him some time and reminders that the transition is coming up so that he feels like he has some control and some say in the situation. If he really likes water maybe you could fill up a water bottle with glitter/toys that he can play with and shake around at the table while he is sitting or maybe even craft a water pillow/bag that you can tape to the table for him to play with at the table similar to this: http://www.teachpreschool.org/2011/08/bright-an...
Just make sure to duct tape everything really well so that you don't end up with a water mess at the table. I hope this helps you a bit and while it may not help his hyper activity it might help his tantrums.

Hi, do you have a regional center in your area? They can help provide a behaviorist to come to your home and support him. It seems he needs a sensory diet. Go to abilitations and look for a weighted vest or lap buddy. Pressure can help a child focus. Also ask his classroom teacher for ideas.

my 4 year old son was just like that up until this past year, where I have changed his diet (we are still transitioning to our goal diet) to include a high dosage of omega 3, removed processed foods, reduced most of the sugars (thats tricky!), balanced out his soy consumption to a currently manageable level.

Also, along with diet you need to increase his mental and physical activity levels, and encourage him to find his own mental stimulation through his environment, not just the water.

So a) get him more active B)go towards a whole foods diet (SCD or paleo are good examples and guides) c)build structure in a very casual and slow manner. Do not attempt to do any challenging transitions or activities singlehandedly, it requires two individuals to manage behaviours.

As a result, if you look at my recent posts.. my son has calmed down a great deal, has found more functional outlets for his water obsessions, is improving in ever developmental way! also may be a good idea to look into vitamin B complexes..

this really requires talking to natural interventionists as there's a great deal of dietary aspects involved in this, and he needs more social stimulation.

I decided to work from the ground up, as though he were new to me and newly diagnosed... its complicated, but not impossible.

He needs you to love his interests as much as he does. and to show him how to have them grow with him.

At 6 years old, he's too old to have tantrums like you describe. But he might not know what else to do. With my boy, I figured out that he reacted in socially unacceptable ways because he didn't know what was socially acceptable. Kids with ASDs love to know "the rules" because they make what looks unpredictable make a little more sense.

If you explain to him that he can express his disappointment in more positive ways or with alternate options ("Aw, rats! Then can I go play ball?"), he might be less likely to go nuclear every time he gets an answer he doesn't like.

Also, he might need to know that if the answer is "no" now, it might be "yes" another time. My son used to worry that "no" meant "no forever," and that freaked him out. Finding out that it was a temporary answer was a huge relief.

One other thing: he should know that he cannot be allowed to harm other people when they give him an answer he doesn't like. Autism is not an excuse for bad behavior. Every action has consequences, positive or negative. Hurting another person might mean he loses his favorite toy for a certain time, or that he doesn't get something he was looking forward to...and (in this mom's free opinion) he should apologize for hurting before anything else happens.

I hope that helps.
