NSBD 

National Second Born Day - a holiday dedicated to the second born child. They are to be rewarded with love and gifts. This shows appreciation to the second child, for being great and helping his/her parents out. The second child is the one to do most of the work, compared to the oldest, since they have a better sense of responsibility. Honor your second child, for they deserve it.

“Happy NSBD! Thank you for helping out your older sister, who didn’t even pay off her credit cards”
