Thank you all for your replies, I was getting a little impatient and rang mum, she is coming up to see what all the comotion is about lol...

Life is Good - TY TY TY that is what I am worried about

...and also, if the bottles are being carried around and one happens to drop and the plastic cover lid falls off (just pushed on) then the teat is no longer sterile - in fact the whole bottle is no longer sterile because as soon as the teat becomes germ infested, so does the rest of the bottle, if you carry spare sterilized teats everywhere you go, which brings us back to the problem of needing to get the seals to seal off the lid where it attaches to the bottle... but then would it be a race against the clock, then that brings us to the argument of the 3 second rule when food is dropped on the floor etc... I don't like it..
