Sour breastmilk, cranky baby

*Sigh* all my hardwork of expressing the breast milk have gone down the drain. Most of the breast milk have gone sour, most likely due to the fact that the storage bag did not close well and the smell of the other food stuff in the freezer went to it. I had to throw all of them away (it's a waste, but better than letting my baby suffer). Even so, she was quick to know that the milk is not good and didn't want to drink it.

Now I have to use the plastic containers (ones that have a cover as well) to store the breast milk. At least I've used that previously and know that it is still well and good for her to drink.
