How long?

Today is DH's first day home alone with LO while I'm back to work, and he has to spend it out of the house due to a family emergency. LO has been EBF until now, so we are sending him with two 2 oz "meal" bags, two 1.5 oz "top off" bags, and one 1oz "snack" bag of milk - I'll be gone for 6 hours and LO is 3.5 weeks old. How long will that milk be good for once it's moved from the freezer to the fridge? We're probably sending too much to start because he won't have access to the stash, but I don't want any to go to waste.
