The little 'o' ring on the diaphragm/top bit of my pump has gone, I've superglued it 3 times now but it's not going to hold. I've seen spares for sale in the US but not in the UK. I can't survive without my pump or my boobs will burst at some point when DD has her moody days. Can anyone point me in a 'spares' direction? Medela website is no use. Pretty please? [bats eyelashes]
