DD is EBF/BLW and in the mornings I give her a bottle of expressed milk to play around with whilst I get ready.
Today I did the same and noticed that there seemed to be a powdery like film left at the bottom. I opened it and it smelt horrible! Not entirely sure how it went off considering I only expressed it 2 days ago and it was stored in the fridge 
Anyways I think she drank about 2oz and I'm really worried. Am currently BF'ing her to try and dilute it as that's all I could think of doing! Has anyone got any better advice? Or even reassurance that I'm not the worlds most neglectful mother..
