Best kid doctor ever!
In the video, Dr. Darden was playing with the kid to divert his attention, who was having his pair of vaccination. The mother of the child was documenting the scene to show to her family the doctor she had found.
The viewers were amazed how the doctor handled the kid and how he was able to administer the vaccine in such fast manner. All throughout the video, the kid was just laughing.
That's how amazing Dr. Darden is. Because of his funny side and expert to his profession, he could easily get the trust of his patient.
