Feeding old milk

mcanant

I have a large stash built up but recently, due to LO change in eating amounts, I am not putting much away per week. Maybe a couple bottles worth. My stash is large from a month to two months ago. In order to use the older milk quickly, should I mix one bottles worth amongst the four she gets while at grandmas during the day? I have only been using old milk on Mondays. TIA
