Avent via feeding cups, are they unsuitable for regular use as feeding bottles?

[bananabump]

I bought an avent via feeding system (breastpump, about ten cups, two teats that fit onto the cups to make them into feeding bottles)

I've been using them to give baby ebm and formula, and just repeatedly sterilising the same two avent cups with the teats etc. I just read somewhere [ here ) that these kind of avent cups can be re-sterilised up to 4 times, is that true? I've sterilised these a fair few times each now.

Do I need to buy regular plastic feeding bottles instead? (he usually only has a bottle once a day)

i think i remember reading that the reason they suggest not using them more than 4 times is because they're quite flimsy
so as long as theyre holding up it should be ok
if you do buy more - they don't come with lids
i use mine over and over again to express into

oh, ok. thanks polarbear!
