As a big sister, It's Ling Ling's duty to teach Fletcher some of the things that she knows. One of those things is the diaper bump. She decided to have both Her and Fletch stand on all fours for the first one before working their way up to standing. She then told him that the tricky part was the timing, as both needed to hit each other's diaper butts simultaneously. While it took a few tries to get it right, they were able to successful get the hang of it. Fletch sure found it fun much to his big sister's happiness.
