It is amazing how everyone gets a little tense when a newborn baby starts to cry at the top of their lungs. I have seen many a parent throw up their hands in frustration when they have tried three or four things to get them to stop and the baby continues to cry.
In this video a little girl about the age of three shows what a master she is in making her newborn brother stop crying. She is at first frightened but she relies on her own wiles and does an amazing job at calming him.
