how big a fridge do i need if i am buying an extra one just for the expressed milk?

I purchased this Farfalla upright freezer which can contain 120L of milk. It has 4 drawers. Each drawer can hold roughly 40 packets. It actually depends on your output and how much milk you want to store. For me, I have an oversupply and I'm finding it hard to use up my milk. I've only filled up two drawers, so I'd say this freezer is big enough for me. Breastmilk can be safely stored in deep freezers for at least 6 months. http://list.qoo10.sg/item/FARFALLA-UPRIGHT-FREEZER-MODEL/414950334

this is only a freezer and not fridge? do you usually need to freeze more or chill in fridge more? Thanks Jamie!

thanks
