D.L.F. went through a long phase of throwing a fit whenever he was told he couldn’t have or do something. He seems to be getting better about controlling his emotions. Lately, if something upsets him, he tells himself, “Stop crying! You must be quiet! [Cupcake] is sleeping in her playpen!”, and then he calms down. It’s pretty cute to hear him getting firm with himself.
I really don’t know where he got the line about “You must be quiet.” It sounds so quaint. T and I don’t say that to him; we might say, “Please be quiet,” or “You need to be quiet,” but not, “You must be quiet.” The only thing I can think of is that in the Corduroy bear books, Corduroy says to Lisa, “You must be a friend.”
