Darina - night pumping / 
We are still volume training Darina. She has good udders, but they can always be a bit bigger! With the vacuum therapy machine, it is quite easy to gain some volume, if the session is long enough. So the best thing to do is restrain Darina to the bed in the holding cell and let the pump run overnight. At first, Darina is struggling a bit, but she soon calms down and even takes little naps. Somehow, udder pumping (as opposed to nipple milking) is quite relaxing to most HuCows, once they are properly trained. Sleep well Darina, let's hope you wake up with slightly bigger udders!
