My daughter is 3 months old and I express and occasionally give her milk from a bottle, ( baby no3 and need the flexability) but I don’t always know when I will need it. How do you store sterilised bottles so that I don’t have to do it every time I need one and delay the feeding time.

  • Sterlised bottles stay sterilised provided that have not been used . Keep lids , teats, caps on all the time and you should be right. You can put them in the fridge for extra precaution but it is not necessary because babies go through so many feeds you will use them quickly and going through the process again .



  • as long as they are cleaned properly and dried well



  • We use an airtight container



  • Bottles only stay sterile for 24 hours. Keep them sterile for as long as possible by assembling them once you’ve finished sterilising, including putting a cap on tightly.



  • Pop then in the back of the fridge



  • I hope you found some advice that helped.



  • Good advice below – hope it helped.



  • Just in the coldest part of the fridge.



  • I hope you found some tips on how to store sterilised bottles



  • In an air tight container or in the fridge



  • hope you found the answer you were looking for



  • I was the same as you and only used bottles occasionally. I’d only use the avent bottles that came with the lid on top, make sure they’re completely dry before assembling them, putting the lid on, and keeping them in the kitchen cupboard. I like the idea of keeping them in the fridge though.



  • I always left sterilized bottles in fridge too



  • Good luck after sterilization I’d throw them in the fridge empty as the cold temperature doesn’t allow bacteria :-)



  • What to do when the items are clean and sterile?

    It is important to consider what you will do after your items have been cleaned and sterilised. Some people will remove items and store them in an airtight container, or others will assemble the bottle (without milk) and store the empty bottle in the fridge until required at feeding time.

    The microwave sterilisers or electronic sterilisers, depending on the brand, will keep the contents sterile for x hours provided the lid is secured and is not opened.

    It is also recommended that whenever you touch bottles and teats, you wash your hands first. In particular, try not to touch the tip of the teat.

    At what age can you stop sterilising equipment?

    It is suggested that you continue to sterilize all baby bottles etc until your baby reaches 6 months of age.

    This information applies for all baby feeding equipment that comes into contact with milk, formula, & breast milk – including breast pump equipment.
