How many times can I re-use expressed breast milk thats been stored in the fridge ?

DS doesn't always finish his feeds he's only a week old so only sometimes takes 1-2oz my question is is it safe to re use expressed breast milk if it's stored in the fridge and how long can you re use it for thanks in advance x

If they have had a drink from the bottle then I dont think its advised to reuse it after 1 hour.
Split it into smaller amounts so it doesn't get wasted

Once. Pump, fridge, heat up and use again then throw away whats left.

No.
Like any foods, it can only be reheated once. You can obviously just decant smaller amounts at once. 1-2oz sounds about right at that age. You can freeze it in ice cube trays.

Thank you all for your responses x
