Numerous videos of a pair of premature twins who can't stop holding hands are melting hearts all over the internet.
Mum Anthea Jackson-Rushford, from Australia, who gave birth to Kristian and Kristiana 12 weeks early, shared the precious moments on Facebook.
In every video the twins - who only weighed 2.2 pounds each when they were born - are always clutching each other's hands.
"He actually holds her hand!" a voice says on the video above. "How is that possible?"
Jackson-Rushford first uploaded a video of her twins on 13 January, showing them hiccuping and holding hands on their father's chest, after they were born at 28 weeks and one day.
The initial video had seven million views and nearly 100,000 shares within a week, with many commenting on how "precious" the moment is.
Documenting the twins progress on Facebook, Jackson-Rushford has since uploaded more videos, claiming Kristian is being a "protective big brother" by always holding his sister's hand.
"As you can clearly see, they can't stop holding hands," Jackson-Rushford wrote on Facebook on 19 January.
She then uploaded a series of four videos of the twins holding hands while fast asleep on her chest.
Jackson-Rushford has said she is posting Facebook updates about her twins' progress to give hope to other parents of premature babies.
She wrote: "We realise it may be a tad bit disturbing seeing our twins with tubes but they are preemie babies so it is understandable and normal.
"I'm sharing photos and videos for the simple reason that it gives hope to all parents out there that even they do just fine.
"I googled like crazy looking for hope when we told we might be premature.
"I would love to see this kind of positivity as a mum that faces the possibility of a premature baby. To all parents that face this, be comforted in knowing that today anything is possible and your babies will be just fine."
