What happened to our youngest child?

Last week Carter was a typically 5 year old Kindergartner. This week...Walt Disney World has turned him into a thrill-seeking nut! At Hollywood Studios he went on the Tower of Terror 5x - 3x in 30 minutes; as well as the Rock n' Roller Coaster which goes from 0-60mph in less than 2 second in a dark tunnel with Aerosmith blasting through neon lights. Today he went on Expedition Everest 6x - 4x in 30 minutes with Sara before breakfast. This afternoon I think it all caught up with him as he looked rather nauseous and ended up going back to the hotel for some quiet time while Logan and Shawn went to Downtown Disney....by dinner he was back bouncing off the walls and planning for his adventure to space mountain tomorrow. The kid is obsessed! Logan - lets just say he keeps to the mild rides which is fine with us. At times he gets a little sensitive that his little brother is going on all the big stuff....but he likes the shows and is still having fun. It is great watching the boys interact with each other and being goofy - they get a long very well!
