Afterpains or severe cramps are common in multiparous clients who are breastfeeding due to the release of oxytocin during breastfeeding. Oxytocin helps the uterus to contract and return to its pre-pregnancy size. These contractions can be more painful in multiparous clients because their uterus has already been stretched and may be more sensitive to the contractions. The pain can be managed with pain medication and other comfort measures such as warm compresses and relaxation techniques.
