Yes, once when I had mastisis in one breast I was hand-expressing to relieve pressure and got some milk on my finger and licked it off before thinking. It tasted very salty so I tasted the milk from the healthy boob and it was very sweet.

So then I used it as a test to see if I had mastitis or not, so I could get onto it quickly. It was very salty. I was amazed my baby would still drink it.
