On March 30, Chase Lykken and his family had just boarded the ship docked at Port Canaveral in Florida before the boy was found unconscious in a swimming pool. Chase was pulled from the water and rescuers began performing CPR.
He was transported to Cape Canaveral Hospital and later airlifted to Arnold Palmer Hospital.
Chase stopped breathing for several minutes and had suffered severe brain damage.
"He has a long and difficult recovery process ahead of him," according to his CaringBridge site.
A journal entry posted Wednesday morning said Chase was making small improvements at Children's. His parents, Chris and Lisa, are taking it one day at a time.
"Our little fighter knows we are here with him...We are rested, positive, trusting in the Lord, and ready to tackle today," the post reads.
Chase's condition updates are also being posted on a community Facebook page.
