lanisoh is lanolin based cream that helps to protect your nipples if they are sensitive or cracked. You get it from the chemist over the counter.
It is good but if you get nipple thrush or cracked nipples it can make it worse! I am using shields now for the first time cause I have thrush and my nipples have cracked. I can't feed at all without them but with them I was able to do a whole feed on the worst side... Get them n give it a go, but maybe try BF without them first and only use them if you have to...

Good luck sweets!
