Ok, so I've never had a great supply...what I pump in one day is used in combo with formula for DD while in daycare the next. Yesterday I pumped my usual three times at work and stored each bag in the fridge, then to transport home I put the bags in a cooler bag with an ice pack. Well I forgot to put the bags in the fridge when I got home and just realized!!! Can this be used for Monday? I know Kellymom.com says that milk isn't bad unless it smells or tastes sour which these packs don't...WWYD? If I have to throw this out I will seriously cry, I have no stash and that means no BM for DD on Monday unless I can squeeze in some sessions this weekend.
