Study limitations
nipple damage, nipple pain, pain
SECONDARY
This is a secondary analysis study based on primary data and respective photographic images on the first and second day after birth. During this period, the nipple pain in initial nipple damage from infants’ first exposure to the breast may influence the occurrence of higher pain scores, while, on the second day, BF women may have familiarized with the breastfeeding practice, influencing the perception of nipple pain reduction. Deleting images was also a limitation. Setting the starting day of nipple damage instead of the postpartum day may provide better results.
