How much expressed milk will I need for my 5 week old?

[newmummy01]

First message I've posted here so hopefully someone can help! My DH and I are off to an evening wedding reception in a couple of weeks when our DD will be 5 weeks old. How much milk do I need to express for this night out? I don't intend to drink when I'm out so only need enough to cover the evening.

I don't know how much it depends on the baby, but my ds was satisfied with about 4oz every 3 hours at that age. I would err on the side of caution though!

Here's a calculator from the Kellymom site which might be useful

I'd say 4-5oz but you may want to leave several smaller amounts so none goes to waste if she wants less. You can always freeze any untouched left overs.

Thanks to you both for responding - that's great! Need to get to work expressing now! Shonaspurtle thanks also for the link.
