I’m assuming you’re talking about breastmilk, in that case I think 5 days is okay as guidelines say it can stay in under 4 degrees for upto 6 days x
my partner did exactly this, 5 days pp aswell. She had a bit of diarrhea but other than that she was fine!
Breast milk is usually good for about 7 days. The CDC 4 day limit is pretty conservative. Of course do your best to stay within the guidelines, but your baby will be be completely fine. Spoiled milk isn’t subtle, your baby would notice and not like the milk
It was 3 am and dark & I was exhausted with him crying. He’s only 3 months old, I’m praying he doesn’t have tummy issues. Milk was in the fridge in a bag. Mixed with fresh day of milk 3 oz. I had to throw it all away because I mixed 1 oz of the old milk into it to complete his 4 oz
