On Friday when I pumped the valve accidently fell into the bottle of breastmilk. Because I was in a hurry to head back to work I told myself I would take it out at home before I stored the milk or when I transfered the milk to another bottle. As it could have been foreshadowed I forgot. I put the milk in the bottle along with the valve into the freezer and now the milk is frozen with the valve inside.
Can I still use both the valve and the milk once the bottle is defrosted for use? Should I do this ASAP?
