I've just started expressing milk and yesterday got an ounce and put it in an avent storage cup in fridge at the bottom at the back of the shelf. I came to take it out this afternoon and it looked like it had curdled - there was milk on the bottom and it was watery on the top. Is this normal?
I didn't give it to DD, but don't understand how it could have curdled in less than 24 hours at the back of the fridge. HV told me you could keep it in the fridge for 5 days!
