SMA milk after 2 hours?

[LowKeyKoala]

I usually use aptimil pre mixed ready to feed formula when we are out but tried SMA from a carton. Poured the whole thing into a bottle to avoid leakage etc, LO had a bit then fell asleep so gave some more nearly two hours after this from the same bottle.

I now realise it says always discard after 1 hour whereas aptimil was 2..?

Is this a problem or has anyone else done it and LO has been ok? Only a few ounces were taken

Honestly, I can't imagine it makes much difference. It's a milk based product that is prone to bacterial growth, but I can't imagine it's so much different that it goes bad an hour sooner on the dot. I suspect they just have different legal teams. Very likely it's fine though.

Advice for all formula is 2 hours after opening liquid/making powder or one hour after starting to drink it. Which ever is soonest.
