I'm honestly wondering now if maybe it was the fresh tomato in the BLT she was reacting to - she was horribly colicky tonight and I had tomato soup for lunch. The only other thing today that was remotely allergenic was that there was soybean oil in some cookies and the Wheat Thins I had today. Is tomato a common allergy?
I think the pp was right about it taking 2+ hours to enter the milk - I think she reacted Sunday night to the BLT from Sun. lunch, yesterday morning to the granola from Sun. night and then last night from Mon. lunch. She ended up waking up at 8 am, sleeping from 1-4 (and that was a fight to get her there) and then finally sleeping at 10 pm. She normally has at least 2, if not 3 naps during the day (nice 2-3 hour ones) so this is definitely reaction. She cried last night like I haven't heard her cry since I cut dairy out - I felt so bad for her!
