Just depends! If he’s due soon, I’ll put it directly in a bottle & give it to him next feed since breast milk is good in room temp for 4 hours but most of the time I dump it into a pitcher in the fridge. Love these glass pitchers btw! We use the blue one for breast milk & the pink one for batch formula — we boil water, add the formula and mix with the pitcher, then it’s good in the fridge for 24 hours.
