How do you go about feeding those newborns 20 oz of colostrum? do you use one bottle and keep reheating it? a bit at a time? I have some in my freezer, but it hasn't been heat treated, should I heat-treat it near the time the first kid is due and then keep it in the fridge? then milk out some colostrum for the next kid? Not having any two-legged kids, this bottle thing will be new to me... AAAK!
