Can you put 2 (cooled) bottles:of expressed milk together in a milk bag to freeze?

I have a bit of oversupply. Not too bad during the day, but at night I have to expel some of the milk from the other breast my DD feeds from or I'd be uncomfortable and I also leak everywhere.

I was told not to do a full pump, or I'd be compounding the oversupply problem, but just to express enough so that I was comfortable again. That's usually about 50-60 MLS (2oz) to make me feel like my boobs aren't going to explode any more due to engorgement.

She doesn't usually take the 50-60ml during the day, but I usually freeze it and hubby defrosts it and uses it at the weekend whilst I go out to a yoga class and meet a friend for coffee or lunch or something.

As she usually takes 120ml bottle per feed, I wondered if I could save the expressed milk from one day, then the next day, add it with that night's milk (so from 2 consecutive nights). They'd both be cooled as I usually just dump what I've pumped into the fridge, then put it into a freezer breastmilk bag in the morning (I'm not faffing with that at 3-4 am!)

Is that possible, so that I have a whole feed per bag, rather than the half feed of 50-60ml

Yes you can do that, I do it although they say you technically shouldn't as it means the first expression defrosts a bit when you add the second milk. But anyway I recommend freezing it as 20ml/30ml ice cubes in a special ice cube tray with a lid. Then you can just defrost what you need and it's less wasteful. It's also easier to store lots of cubes in a flat tray, you can fit more in the freezer

I think @Mummy1608 that OP means not freezing the milk from day 1 and waiting til day 2 and freezing together as one 'batch'.

@Pitstop1986 I would do as you suggest, I know people who do. I haven't yet got to the point of freezing any breast milk, anything I can express is used quickly but I'd like to start storing some and has asked breastfeeding support for advice on it.

Can I ask how old your baby is, mine is 8 weeks and now taking about 140ml and not sure how much it will keep going up so maybe if you also store some in an ice cube tray it can be added as the feeds increase. I ordered some lidded ice cube trays for that purpose.

She's also 8 weeks. If DH gives her a bottle, she usually takes 120ml, so I figured freezing in 120ml bags would be ok, I didn't think about the possibility that her appetite would increase.

Ice cube trays is a good idea. Do you get a special one specific for breastmilk @Mummy1608 or can you just use a standard ice cube tray with a lid and sterilise it before putting in the freezer?
