EBM - how long in the fridge?

[needsadviceplease]

How long can ebm keep in the fridge for? I've read times ranging from 24h to 5 days. I can only express 1-2oz a day and need to leave a 4oz bottle, I'd prefer not to have to freeze really.

TIA

5 days IIRC, kept at the back of the bottom shelf where it's coldest.

NHS website says five days.

Thanks both! I think its the tommee tippee leaflet that says 24 (or 48??) Hrs, I'll take the nhs over tt.
