Kids are creatures of habit. Repetition is heroin for them and they always need a fix. How do you think the Teletubbies pull off “Again! Again!“ without a rebellion? You have to be very careful interacting with underage folk because something you do once you’ll have to do a million times. And there is no rhyme or reason to what that thing
will be. A bazillion clips on youtube showing babies losing it over some completely random sound prove that. I smooched Keilana once during the chorus of “Kiss the Girl” from “Mer-naid” and, forever after, had to kiss her each time the song played--even if I was driving. When Connor was tiny, the sound of tearing 
paper would send him into hysterics--so we did it every chance we got. I must have opened a can of Pringles a few times to keep Addie quiet during Walmart trips, because the one time I passed by the food aisle, there was broken-hearted wailing. And now Scarlett. Maurice Sendak’s trip through the calendar Chicken Soup With Rice, about a little guy who never tires of the comfort-food staple, is when it happened. According to the book, August is so hot that the little boy will turn into a cooking pot and simmer his own soup. When Scarlett reached out to touch the page, I pulled her hand back and hollered, “Ouch!” She was laughing so hard it took us about ten minutes to go to the next page. Toddler humor, go figure.http://www.amazon.com/Chicken-Soup-Rice-Book-Months/dp/006443253X
