Storing breastmilk in bottles with teats?

[PurpleCurtain]

A bit confused - can I pour expressed breastmilk directly into the mam bottles with teats that I'm going to feed baby with, and store in those in the fridge for the 5 days I can store breastmilk in the fridge for? I thought I could - and this is what I've been doing with my baby since birth (we started by exclusively pumping, now have zero to two pumped bottles a day) - but have been told that this is wrong and that I should only be storing it in "storage bottles" if it's for more than 24 hours as the drinking bottle won't stay sterile for longer than that? I'm confused though as surely the storage bottle also wouldn't stay sterile for the full 5 days in that case anyway?!

Where do you buy these super bottles that stay sterile for longer?

Although I'd be tempted to resterilise the teat if they were in the fridge for a few days

Well this is my confusion - how do you store breastmilk in the fridge for 5 days if it isn't possible for a storage vessel to stay sterile for 5 days?! Hmm changing the teat if more than 24 hours does seem like a reasonable solution, just need to make sure I'm keeping enough sterilised teats to hand now I guess!

You can get little caps for some bottles that turn them into storage containers. Dont know if they're freely available these days

Mam used to have small white lids that came with a set of bottles for precisely this purpose although we were on child 2 when we realised that's what they were for

I wouldn't store with the teat on as it's not sealed but you can usually buy lids for bottles.

Yes I wouldn't leave the teat on as the milk is then exposed to air. You can get caps for the bottles though and use a sterilised teat when it's time to use it.

Alternatively I stored mine in breast milk storage bags inside a Tupperware box which took up less room and meant I could freeze it if I had surplus.

The advice you were given is correct. It can be stored for more than 24 hrs if in a sealed bottle as air naturally contains bacteria.
The teet allows air in which will spoil the milk quicker.

The mam bottles have clear caps that go over the teats though? I have never used any type of bottle so i dont know if thats typical or not. Are these caps good enough or are they not considered air tight? It will be so much easier if we can just store in the bottles, with teat and cap on, until ready to use, but I cant find an answer anywhere!

*any OTHER type of bottle

No it's not considered air tight enough and you also have quite a bit of space.

You will probably find your local BF group on Facebook a mum has old/spare hospital bottles (especially if they had a baby in neonatal unit). I used to store in these then would pour warmed milk into the bottle. It also meant that there was less wastage as typically okly needed 70-90 ml
