When Z gets fussy, but it's too early for a nap, there are a few go to things that will placate him. One is giving him access to crackers (really, anything edible would probably work.) But since we don't want him to turn into a 100 pound baby, we usually resort to some of our other "tricks." Here is one. My mom tells me that when I was a baby, my babysitter used to do this to me and get a huge kick out of it. I actually remember her doing it to my baby sister. As you'll see though, once you start, stopping isn't an option.
