Gold Coast (Australia) - It' s no secret that twins have a very special bond. Nevertheless, what a mother in Down Under observed over the baby monitor was completely unexpected for her: Early in the morning, one of the cribs of her twins (2) was suddenly empty. The other crib, however, was filled with sweet scenes.

It was around 6 o'clock in the morning when something happened in the nursery of twins Harper Willow and Declan James Finn .

While Declan was still slumbering peacefully, his sister had decided without further ado to pay her brother a visit.

The two-year-old climbed out of her bed and into Declan's and then tried to wake the boy up.

However, the girl was extremely gentle in her approach: Instead of smacking him across the head in toddler fashion, Harper gently patted her brother's back and then babbled, "Hi, hello, Declan!"

And it gets even cuter!

When Declan refuses to be woken up, Harper starts by naming a few of his body parts - "your baby bum" and "your curls" - before finally snuggling up close to her brother and continuing to stroke his face and back.

"I wasn't expecting this when I looked at the twins' surveillance screen," writes mother Sinead on TikTok , where she posted the footage of her children . Although the Australian's video has only been online for a day, it has already been clicked on more than 2.4 million times.

No wonder, after all, this moment of absolute sibling love gets right under your skin! Sinead is also touched: "My heart wasn't prepared for this ..."

"This is the most beautiful thing I've ever seen on the internet, I think," commented one viewer. Another thoughtfully writes: "I thought about how they will feel as adults when they see this and I realized how overwhelming it is to have real footage of yourself as a baby. To experience yourself as a baby..."

In the end, Harper actually managed to wake her brother up thanks to her stubborn nature. Declan didn't really find her wake-up command funny at first, but then let himself be cheered up againby a tickle attack.
