M.,
This info coming straight from a Lactation Educator and Certified Breastfeeding Counselor....
PLEASE DO NOT do what you just mentioned to your breasts or nipples. The last thing you want when you begin to breastfeed your baby is a hard tough unforgiving nipple. What you do want are soft supple stretchy healthy nipples.
To prepare for breastfeeding all you have to do is...
No more soap or lotions or potions on your breasts. Don't scrub them AT ALL. (I know when you shower the soap will run past, that is fine.) You have, on the surface of the areola, some small little bumps that have been becoming more noticable lately.. right?. They are called Montgomery Glands, their job is to prepare the nipple for breastfeeding. They make an oily substance that you can't see or smell, BUT your baby CAN!
Now, if you are getting itchy or dry nipples before baby comes, you can use a Lanolin cream *(NOT if you are allergic to wool.) like Lansinoh, PureLan, TenderCare Lanolin by Medela, or better yet Motherlove Herbal makes an amazing nipple cream with NO lanolin in it.
Third I'd recommend a breastfeeding class outside of the hospital if you can find one. Where are you? IF you are in Arizona, I have class here. If not take any class - it's better than no class.
And most importantly, you can expect breastfeeding to be a bit uncomfortable for about a week (hormone changes cause breast tenderness), that doesn't mean toe curling, dreading feeding, or you crying while feeding the baby. If these happen you get to a Lactation Consultant as FAST as you can and get it fixed!
Good Luck,
