How many Oz to leave breastfed baby

[Motherofmonsters]

My DD is 10 weeks old and I need to leave her for 5 hours as I need to attend a funeral and wake.

I'm not sure how much milk I would need to pump to see her through. Roughly how much do you think she would need?

We've tried her with a bottle and she is okay with it

Thank you

about 120ml a feed is what mine liked at that age but its hard to tell each baby is different.

When pumping massage your breasts it helps with the flow ,just put on your favorite tv show and relax with a cup fo tea that usually helps me.

I used to leave a lot more than I thought I'd need. I went for about 6 hours the first time and MIL had Ds, he drained the first bottle in an hour of me leaving even though I fed him right being going.
So he had the second bottle a few hours later. He was about 4 months at that time, I used to leave as much as I could each time all split into bottles in the fridge. Anything not used I froze, then MIL would defrost bottles in a jug of hot water as she needed them as we got used to me leaving.
