One laughing baby is often what you need to turn your frown upside down. Well, this video will provide you with four and make your smile last all day. 

This hilarious video shows four adorable quadruplets sitting at the table with dear old dad and it is a funny site to see. As their father starts making faces, all four cannot help but laugh all together. Their laughter is so contagious that you cannot help with smile and laugh along with them. 

Got to love those laughing babies.
