Tricks with Milk

I decided to buy Anna some drinkable yogurt (YoBaby) last week and she loves it. Little does she know that I've been mixing in some whole milk in the yogurt the past two days and she still loves it. I'm hoping to keep increasing the milk contents each day until she is drinking mostly milk. I feel kind of sneaky, but I think in this case the ends justify the means. For now I am still calling it "yogurt" for fear that she'll reject it if I call it "milk." (Like the time I made homemade macaroni & cheese and called it "macaroni & cheese" and she looked at me like I was trying to feed her poison until I called it "pasta" and then she thought it looked pretty good!)
