Letting the fresh air dry the BM into them is great. After every feed let them air dry before doing your bra up.
Make sure your BP's are changed often, so they are kept dry.
A little topless sun can help, but don't burn.
Lansinoh is great stuff, but probably better if there are cracks maybe? It does help then.

I found the first 6 weeks are the hardest. Just go a day at a time, then a week at a time & don't have the FF on hand & it will get easier. The nipples do toughen up. Trust me you'll be greatful for that when baby is trying to do summy's while attatched at about 6 months old!!
