Was v proud of myself as I actually made up three bottles of formula for tomorrow (followed guidelines, use freshly boiled water, cooled straight away in bowl of icy water). Stupidly forgot to put them in the frigging fridge!! They have been in the water with lots of ice packs for about 90 minutes so they're cooler than room temp but not fridge cold. Now in back of fridge. Can I still use them?? NHS guidelines say use within 1hr at room temp, 4hrs in cool bag with ice packs, 24hrs in fridge - sadly the guidelines don't cover stupidity
