"I want this warm hug once again", his widow Valeepoan said on Instagram, posting a photo of her and Saman embracing. We are so happy to hear that our son is out of the cave and to welcome him home.
"I was exhausted", he said.
Meanwhile, reports say the boys and the coach were sedated to stop them panicking during the risky rescue.
Dr Harris was the last person to come out of the cave. The children were well taken care of in the cave.
He added that it's important for the boys to stay connected throughout life because they're each one of only 13 people who went through a unique nightmare.
With the boys still recuperating in hospital, US-based production companies have already taken an interest in turning their story into a motion picture.
The boys have been given health cards, which they will continue to carry for two weeks after they leave the hospital, in order to jot down any issues.
Footage released by the SEAL team showed seemingly prone boys - at least one in full diving mask and wetsuit - being stretchered along the jagged passageways.

The "Wild Boars" football team got stuck inside the cave on June 23 after flooding caused by heavy monsoon rains blocked the entrance.
He was the last man out of the cave Tuesday but emerged to tragedy, learning of his father's death shortly after the rescue had completed. "Without him, in this operation, I don't think we could have succeeded".
Chaiwetch Thanapaisal is director of Chiang Rai Prachanukroh Hospital.
However, good news may be coming for these Wild Boars.
The rescue sparked jubilation with Thais heaping praise on the rescue team of foreign and local divers as the triumphant tagline "Hooyah" pinballed across social media. When divers reached them later, they brought additional food, water and blankets. "They have to help each other".
Kanthawong said he just wanted to support the team now that the players were out.
