Personally I have given my baby the same bottle if not finished a couple of hours after initial feeding. Lids are always used to cover the teat and it’s left in a cool room (our kitchen). It’s personal choice tbh I always just make sure the formula is made properly according to the instructions
As far as I'm aware it's 1 hour if it's been drank out of/touched babies lips and 2 hours from the time it's made if it's an untouched bottle. I wouldn't risk it personally but it is frustrating when the bottles get wasted! X
I do 2 hours even though he has touched it. As you can see some people follow the guidelines, some don't. Same with all baby stuff, find your own way!
Bacteria can grow once saliva has touched the bottle that’s why the say discard after 1 hour of being used. It’s 2 hours for unused formula xx
