Different babies will respond differently to different things and especially when it comes to making them stop crying. 

Some prefer to be rocked or bounced, jiggled and wiggled but this baby has only one preference and it really is the funniest thing to see. I am sure the father is proud at was makes this baby feel more at ease. The real question is how did they even find out about this trick. Either way, the only thing that makes this little peanut feel better.... The Star Wars Theme Song! Yup, that's correct! 

May the force be with you little child!
