My LO is 4 weeks old and I've started to express my breastmilk. I don't get enough from one pump to fill one feeding session and have to pump 2 or 3 times to fill a bottle. Does anyone know if I can mix breastmilk from different sessions in one day? Can I store in fridge and add to it during the day as I know breastmilk can get a bit funny when left at room temperature.

It lasts 48 hours in the fridge so if you use it within that timeframe then I would imagine it’s ok but if you’ve mixed it and it’s been 48 hours since your first pump you’ll have to throw it away

Yes my midwife said you can add to it so long as you go by the date you started it x

Breastmilk can stay at room temperature for four hours! I pump too, and I'll pump once then again two hours later in the same bottle, then put that in the fridge!
If wanting to mix, place it in the fridge first so both are cold when you mix them together if that makes sense?
I've read mixing room temperature and cold breast milk can be a feeding ground for bacteria and milk can go funny and make LO sick!
So as long as they're both the same temperature when you mix them together it's fine!!
Hope that helps xx

I'm the same! I can only really pump around 25ml per session so I transfer to a breastmilk bag and date it. On the next pump, I store in the fridge for at least 20 minutes and then add it to the bag x
@Gabriella makes sense. With the pump do you need to sterilise after each use or can you pump into same cup during the day. I use momcozy.

I read as breast milk is sterile , you can rinse after use (depending on brand I guess) and then sterilise once day. I sterilise once in the morning and then the evening x

If you have a healthy term baby then you don't need to sterilise the pump every time - I wash mine with hot soapy water (as per the instruction of the particular brand) and sterilise 1 or 2 times a day. I do sterilise the pots I keep the milk in though. And you are fine to mix the milk provided is the same temperature.

If it's the same day I'll just rinse, otherwise I'll sterilise after each use! (But aparently you don't need to sterilise after each use though)
I haven't heard of momcozy, I use medela and so far it's been pretty good, in 10-15 mins I'll get between 90-120ml!!

Store what milk you get in collection bags then put together when your ready to feed in a bottle xx

You have to mix the breastmilk that is at the same temperature for example, room temperature to room temperature and refrigerated to refrigerated.
