Hi since it is said to be disposable, have any mummies reused it? If so, how often do u change them? Cos it really doesn't come in cheap. I rem using those really disposable plastic kind that clinic or hosp used for patients to consume liquid medication but my question is how do we go about cleaning and sterilising it? Cos i was first introduced to cup feeding by the nurse in Mt E, and she gave us a cleaning tablet, just use alittle bit of it to be mixed with 125ml of water to sterilise the cup. But for the medela cup, can we use hot water to sterilise it? Need all possible information, as im getting bk to work soon. Thanks mummies for ur inputi got mine from TMC parentcraft centre at $3 each
