I tried 'Lansinoh' when my B was born. It's very sticky, but very effective because my nipples were actually cracked. So I think you can use it if your condition is very serious.
Recently, I have a different problem. My nipples are fine by by breasts are very dry (I think because I massage it all the time to prevent blockage.) On Saturday, I bought Swisso Naturlich Breast Care Oil (for breasts and nipples also). It's quite good and although it's oil, your skin quickly absorbs it so it will not be sticking to your clothes/bra. It claims to be able to increase milk supply too. I feel that everytime I pump now, I can have around 15 to 20 ml more milk. But I'm not sure if this breast oil is the reason on not?
