Lansinoh Nipple Cream really is a must have for a breastfeeding mother. Starting out, even though we had no latching problems, my nipples got very sore and cracked. After the first week I was in agony and was thinking, "How can anyone do this?". My mother gave me Lansinoh nipple cream, and it works! With one application you get immediate relief, and can see the healing process start. I continued breastfeeding with the help of the nipple cream, and still am 11 months later. I didn't need it after the first month but it would have been a horrible experience without the cream! I was also worried that it will affect the baby but there were no side effects.
