She is fine. Just fine. Her measurements were normal. She weighs six and a half pounds. There is no answer as to why the external measurements have shrunk; one guess, from the NST nurse, is that she "must have twisted herself up all funny at the doctor's office just to scare you." Seems as good a theory as any.
I have cried with relief exactly twice in my life: first when the amnio results came back, and then again today. If she makes it out safely, I'm guessing there will be a third time.
I didn't realize till now how close simple relief comes to joy for me.
