We try to do physical things. Take them to the park where they can ride their bikes all around. Yesterday DS6 and his 2 year younger brother rode their bikes for 1 1/2 hours. I thought that would have burned off some steam. But, no...after that he still wanted to run around the block, it is 1 mile...I am exhausted too. The younger is more into the discussions, predictions of "what will happen after" type stuff. It goes on and on.....you are not alone...
