I watched several programs last night with indepth information about this past weekend. In fact Jett and the Travlota family and friends all went boating all day the day before he died. He was very tired when they returned and he went to bed. HE normally slept 12 - 16 hours a day. They not only had the two nannies who shared his quarters, they had a baby monitor to alert them if he moved around and a bell on the bathroom door to alert if he went into the bathroom. No one heard the baby monitor or the bell. (being a boater I can attest after a day on the water and in the sun people sleep very sound). The last time anyone actually looked at him he was sleeping. Sometime he got up and went to the bathroom, hard to do a timeline because people were sleeping, just didn't hear the monitors put into place to keep tabs on him.
I addition to boating he was seen swimming and playing with his father in the water during the vacation and we have all seen picture of he and Kelly walking on the beach. He was not a bed-ridden invalid, they tried to give him as normal a life as possible, but his seizures were severe and became more frequent and uncontrollable == even when he was taking the meds. They evidentally didn't do any surgery to try and aleviate them.
