Uh-oh. Could I have made dc unwell?!

[Cones]

Dc has just had a smoothie carton (Kids individual one and it’s been in the fridge).

I’ve gone to throw it away and saw the best before was June. Mum fail

Anything I can do to stop any I’ll effects?

ill *

Best before or use by date? BB is fine to use after the date.

It was best before!

DC will be absolutely fine. So much sugar in those, it acts as a preservative.

Give them a load of water if you're worried but they'll almost certainly be fine.

If its a tetrapak it'll still be good for years! They don't even heed to be refrigerated before opening (supermarkets waste so much electricity presenting these things to us in refrigerated cabinets).
Of course they're nicer to drink cold and if slightly past bb date as with this just make sure it's all gone in one go.
