The fix: Stay calm! "When I was breastfeeding my first baby I would totally panic at the first sign of a clogged duct, and that made it so much worse," recalls Wilhelm. Try warming your breasts with a washcloth, massaging them a bit, and then doing a feeding. "I found that the baby was much better at unclogging me than my breast pump did," says Wilhelm. If it doesn't do the trick, try a hot shower and manually expressing some milk. As she says, "That almost always leads to improvement!"
