Or is a dishwasher on hot enough?
I'm trying to decide whether I need a steriliser amongst various stuff I'm borrowing for DC2. I'm not particularly planning to express, but I was planning to collect the excess leakage in the early days, and if I need to pump a bit to relieve engorgement, I'd rather stick the milk in the freezer than chuck it.
SIL has a steriliser I borrowed last time, but if I don't really need it, I'd rather not clutter my house with it (but I can't be doing with boiling things in saucepans either).
