I maybe overthinking however I know you don’t want to combine fresh milk w regeriatwd nilk right away til it cools. So if I pump at 7am and then not until 9 pm, once the 9 pm cools I might not get back to it til 5 am is it too long to leave in fridge to combine before I freeze it?? Sometimes I have 2-3 oz that I would like to combine before freezing but unsure how long can last I’m fridge before freezing
