Question from someone who's not a parent and doesn't know a whole lot about newborns, but is it possible she had two diaper bags? Especially if it was her second, maybe she had two (or he thought she had two when she was first discovered as not around -- some men really aren't tuned in to how much stuff a newborn needs even for four hours, he could be one of those 'I'll leave it to you' dads-of-a-newborn) so she didn't have to constantly change from in the car to visiting neighbours/friends etc.?
I know people have said you get more relaxed with the second, so is it also possible she would just throw what the baby needs into some sort of bag just for going down the street, especially if she was breast feeding and didn't need all the bottles etc.? I don't know why she would do that if the diaper bag was in the house, why wouldn't she just grab the to-go bag, but baby brain, etc. can make you do weird things or maybe the diaper bag needed refilling and she just didn't want to do that right that second, I know I do that with my gym/exercise class bags.
Quietly watching the thread, not my first rodeo though, just asking about the possibility. (And sorry if this has been asked or mentioned, like many I woke up to follow this and found literally 30 unread posts ETA: Pages, not posts, d'oh.)
