Lanoline cream is lifesaver for me

Rub breastmilk on them.

A nipple shield might work deeping in what type of pain your having and even if they aren’t dry or itchy you should alwyas moisturizer them with vasalin or something.. a lot of moms don’t do it and it could be helping so much.

Warm compresses and pushing through... it was super painful the first couple weeks but warm compresses and hit showers really helped me

You can’t numb it, you just have to make sure he is latched correctly and keep pushing through. Your nipples get used to it.
