Having three, I still think that the tabula rasa might be the proper was to look at it. The expectations of infants follow from their interactions with the world. And those are firstly the interactions with their parents and family. Outside of the very basic needs (food, drink, emotional comfort) you get the children you make. Not to say that all children react the same way to the same parenting, or have the same expectations. But you do mostly create their value system that governs their expectations.
