I keep in cooler bag and store in fridge. My limit is to let child drink by The following Wed. If not, at any time before Wed, I will quickly transfer to freezer and let child drink asap.
What do you mean by on friday? Just pumo and store like how you usually do? Not sure if i understand your question correctly.
Same as every other day? Store in fridge in office and chiller bag with ice pack on the way home?
