Howling:Another River Song speculation

I just thought of something... If I'm not mad (or I've missed something), if you've noticed... All times during Series 5 & 6, everytime Eleven, Amy, and Rory have met, River has not once wondered who Amy is... She seems to know Amy everytime, even when she doesn't know certain things about the Doctor. I truly believe that Amy is River's mother. Any thoughts or remarks?
