More lessons on the brain and children....

Here are a few more strategies from tinabryson.com. 
One of the lessons that she teaches her parents, and teachers and others is to learn to read the child's nonverbal language.  Is the child being clingy and insecure?  Teach them to understand how it feels to be brave vs. insecure?  How does their body look when they are insecure?  How does their body feel when they are brave?  There is a great deal of activity going on in the brain when the body is understood and how the positions affect our state of mind (this works with older people also).  Here are a few tools for the car.  Find an exercise ball that will fit in between the two seats.  If the child is having a hard time after school, then this is a good way of releasing this pent up emotion, by kicking it with their feet.  Are they hungry?  You can also use an exercise ball to roll up and down the body.  One other strategy is to breathe with the child.  If you can slow down the breathe then they can mirror this activity.  There is such a thing as mirror neurons. 
Here is one more strategy.  This therapist calls it chasing the why?  Why is the child behaving in this manner?  Many times they do not have the right words to explain why.  Are they over-activated in some situations?  Is it because they are sensitive?  Keep looking, they are not always trying to be manipulative.

Try LENS neurofeedback.  It helps the brain to work correctly, it reduces the interference.
