In the clip, John is seen gently cuddling and rocking her younger sister, Clara, to sleep. He did it while waiting for the results of Clara's RSV, Strep, and Flu test.

Clara has achondroplasia, a bone growth disorder that results in disproportionate dwarfism.

The footage also shows the baby girl sucked on her thumb as she falls asleep in John’s arms. It seemed that she feels safe with his older brother. She looked very peaceful.

Since the video was uploaded, it has already amassed more than 3 million views and has been inundated with comments.

A lot of netizens praised the strong bond between John and Clara. Most people also shared their hopes for the baby girl's full recovery.
