How many Oz does your 3month old drink in one go

[Motherofmonsters]

I'm going in a spa day tomorrow and I've been pumping milk for my DD whose 3months and I'm having a slight panic on how much milk I should leave her with.

How much would yours drink one go. I did a bit of googling and some People said 8oz every 2-3 hours but that seems loads.

I've got 11oz so far and should be able to get another 4 in the morning. I'll be gone about 7 hours.

General rule is 2.5oz per pound of weight per day. So if you know rough weight can calculate from that. I found little feeds for our Dd. So I would think if you fed before you left and leave that amount that will be ok. Hope you have a good day
