Expressed milk question

I read it’s the fat/sugar content and the calories in the milk that change throughout the day (ie more fat at night to keep them asleep longer) but to be honest I express at different times of the day and mix them in the same container. So whatever I have from that day whether I expressed it at 8am or 8pm goes in the same bottle and it doesn’t seem to make much of a difference for my baby.

It’s to do with night milk having more sleepy stuff than morning milk, however I exclusively pump and combine my milk into larger containers for storage and there is absolutely no issue with my little guy and he was prem so the rules are a bit more strict!

Interesting, I didn't know of this fact/suggestion. I also mix mine that I store.
May I ask...when your partner feeds with bottle, do you pump at the same time to keep up supply? If so, is the point just that your partner bonds with baby?
A few times I've had someone else feed the baby at night so I could "rest" but it hardly worked because I still had to pump to avoid engorgement close to the time anyway.
I'm just trying to understand if I'm missing something.

I didnt know this untill my baby was around 5 weeks old, told the HV he was waking loads at night and she asked if I was giving night milk at night....I wasn't. I then swapped and it made such a difference in how long he was sleeping between feeds xx

hi Sophia so not always. Now my milk supply is fully established (10 weeks) I don’t get the engorgement or rock hard boobs that I used to 😅 previously as soon as I hit the 2 hour mark since a feed I would feel it. That’s no longer the case thankfully.
For example I planned to pump late this evening but was too tired and I’ve just fed my boy and it was fine. Generally I aim to pump during when I would feed him as this is best practice but I’m not going crazy with it as if defeats the purpose of a rest.
I should also add I’ve got the MomCozy 12 pro so for me if goes in my bra I don’t have to sit about and wait, I got about my business and 15 minutes later just pop it in a bottle or freezer bag.
