Many, many years ago, there was not formula available and many women suffered through terrible pain while breast
feeding. It is true that your nipples toughen up over time and breast
feeding does become easier. When I was pregnant, my OB told me to massage
and pull on my nipples every day in the last month of pregnancy, to toughen up my nipples. He said that breast feeding would be easier.
Both of my kids lost interest in breast feeding very early on.
