So I have a Tommee tippee steam steriliser and I am confused about it... I have been sterilising the bottles and then once it's finished I take all of the bottles out and put the tops and the lids on the bottles and then they are there when I'm ready to use them but it says on the tommee tippee website "When the sterilising cycle is finished, either removed contents and use straightaway or leave the lid closed and contents will remain sterile for up to 24 hours" which doesn't really make sense as everytime you take a bottle out you have to keep sterilising all the other bottles? How would it work if you were to go out for the day ? You need a lot of bottles, so obviously you can just put all the tops onto the bottles once the sterilising is finished. Don't want to sound stupid but I know this is sounding stupid haha.
