Dr.Robert Hamilton from Pacific Ocean Pediatrics advocates this technique that is supposed to calm crying babies in an instant. Dr.Hamilton showed off this baby-calming method in a video on YouTube with two toddlers who were extra-cranky after receiving shots.

What’s even more surprising is the fact that the technique not only worked –but it worked within seconds. 

Hamilton added that if your baby still doesn’t calm down, it could be because he or she is hungry or sick.

Ready to try it out on your kids! What say?
