Every child has their quintessential rituals.
Sometime around when my son turned two- he developed a love of "Yo-yo". I think it started as a love for drinkable yogurt, then a mother who refused to pay outlandish prices for drinkable yogurts , so she started mixing milk and yogurt together in a 1:1 concentration to concoct a homemade thrifty version and thus began "yo-yo". Some people wake up to their cup of coffee- for my 2 year old it's "yo-yo". A day doesn't pass without some. I can't knock it-- its healthy and nutritious, a good source of calcium and protein. The catch is has to made made in one of these 2 special style cups leftover from kids meals (triangle lid with the hole spout). My son always prefers the dingy Moe's cup, because he says it is "more beautiful with all the vegetables on it", to the classier crayola cafe one (hauled back from a Kansas city trip one year).
