Two weeks to go.. BF

Is there anything I can do to ‘harden’ my nipples up in these two weeks! They are so sensitive and swore at the moment I really don’t know how I’m going to attempt to breastfeed 😭 I’m producing white stuff out the little lumps and my actual nipple is starting to leak colostrum so I know I’ll be fine with the milk it’s just how to manage the pain. I only lasted 3 weeks with my first, I just couldn’t bare it! The blisters and bleeding was awful! I really want to be able to do 6 months this time! Any tips please?
