Sometimes this happens because the flow has slowed down while the duct was/is plugged. Baby likes the fast flow, and the plug interferes with the amount or the speed or both. So....work to clear the plug: massage, heat, warm showers, nursing, pumping, over and over. It may take several days. Meanwhile, dream feed your baby and try to not stress it.
