Keep Those Breasts Warm!

Today was supposed to be Lumi's first excursion out (to the nurse's office for a weighing - not the most exciting event), but when the temperature went below -20 this morning (that's -4 fahrenheit!) the nurse called and said she could do a home visit instead.  Anyway, among the advice she gave us today is that though I am allowed to go for walks outside, I need to make sure to keep my breasts warm, because it's easy to develop a breast infection when it gets this cold.  I don't know the physics of that (I'm picturing a frozen block of milk in the ducts somewhere backing things up) but I made sure to bundle them up when I went to the store.
