Koko Supermilk HELP!

[Anon987654321098]

Anyone use this for their little ones? Pretty sure we've got a bad batch. DD was sick Friday and yesterday, no diarrhoea. Think it's the milk. I tried it and it tasted weird...I've tried our other cartons and convinced although they're better they're weird to...but I don't drink it every day so can't be sure....think it's not as sweet and leaves an after taste...the use by is 5/4/23 and batch number is F23400

Anyone else got this batch and think the same?!
