I found I had very sore/sensitive nipples during late pregnancy and in early feeding. If there are not cracks and you can rule out thrush, there is always the free 24-hour breastfeeding support line for any questions you may have -the number is 1800 686 2 686 (1800 mum 2 mum). Sounds like you are doing fine - I m sure you will find it easier as your baby gets older
