Also, a pregnant woman who is told that there is even a metaphorical possibility that she'll die in childbirth, will ask immediately about the baby. Pregnancy involves a whole new level of fear, at least that was my experience (and unlike Padme, I didn't have to worry about my husband being killed in a war). In a later conversation, the one where she tells Anakin that he's been moody lately and he says something about finding a way to save her from his nightmares, she says dismissively, "So that's what's been bothering you." I really did not think she took him seriously beyond that brief second after he mentioned it. Maybe the PP is right and she decided she couldn't help him, so she decided to distract him. But as far as her getting him to ask Obi-Wan for help, I understood her to mean, "Maybe Obi-Wan can help us hide on Naboo long enough to have the baby and then we can both keep our jobs." Not that she thought Anakin should go to Obi-Wan because he had a prophetic dream.
