The time it takes to wean depends on your baby's age, the number of times you are breastfeeding each day, baby's willingness to wean, and your body's response to weaning. To avoid plugged ducts, mastitis, and breast infections, it's best to wean gradually. Eliminate one daily feeding at a time, allowing a few days in between for your body to adjust. (This amounts to dropping one or two feedings per week.) During this time, if your breasts become uncomfortably full you'll need to express a small amount of milk to ease the pressure.
