Although I'm planning on breastfeeding, DH and I bought an Aotamil starter pack of ready to use disposable bottles of formula with teats. It says on the box to store in a cool place below 25c. Which has been fine in our home apart from the past few days. I'm sure it's been hotter than that in recent days but I didn't think to go and put them in a cooler place, not on a kitchen shelf where they have been.
I believe they're ultra heat treated etc but I'm wondering, should we not use them now?
