Fridge door left ajar - worried about baby's milk

[Strawberry06]

I just went to feed my baby at 3am and came down to the fridge door ajar. It must have been like that since about 9pm so 6ish hours.

It ususlly beeps to let you know it's open but it wasn't so I'm guessing it was closed enough to not detect and I don't think the light was on. Our kitchen is also quite cold.

I checked everything and it still felt fairly cold but I'm worried about my baby's milk bottles. I make them up in advance which you're not supposed to do under normal circumstances! They are stored at the bottom/back which is the coldest part of the fridge but equally I'm worried they'll be no good.

I checked it after I fed him and it's making noise so I don't think it's broken, probably working harder?

Just don't know whether to bin the milk

If in doubt then you have to bin. Sorry.

It wii be fine, breast milk is 37 centigrade until used.

How is that relevant?

How old is your baby?

If over 6 months then I would use it personally, that's obviously not the guidance but I'd just use my judgment on how cold they stayed.

If still a tiny baby then I'd bin it.
