In response to bullet point #5 of my post below, I did in fact get the exact lecture # I thought I would when I talked to my MIL today. I had to bite my cheeks to keep from laughing. She did add a newer lecture though:
Lecture #2,343,653 - Always go with your motherly instincts. Don't ever second guess yourself. As a new mother you will tend to second guess what needs to be done for your baby, but you should always go with your gut.... blah blah blah... swine flu... blah blah blah....
Just for the record, I don't second guess my motherly instinct. I'm smarter than that. 99 times out of 100, my instincts are spot on, so I trust them with my life... literally.
