It is normal for your breasts to feel full and heavy during the first few weeks of nursing, but if you find that you are feeling discomfort beyond that time -- specifically, your breasts feel hard and uncomfortable -- you may be experiencing engorgement. The cause is usually inadequate milk removal. For example, your baby doesn't nurse often or long enough and your breasts become overfilled with milk. How to Avoid It: Nurse your baby often -- eight to 12 times a day with both breasts, if you can. Don't skip feedings, and continue to nurse your child during the night as well as during the day. Be sure that your baby is positioned correctly and is latching on well so that your breasts are emptying of milk. How to Treat It: Express milk between feedings, either manually or with a breast pump. Take a warm shower or place a warm compress on your breasts to encourage milk flow. Some doctors recommend using a warm compress while nursing and following up with a cold compress between feedings. If you are severely engorged, warmth may aggravate the situation (by increasing blood flow to the area), so consider trying cool compresses as you express the milk.
