Milk left in the breast signals the breasts to make less milk. Do not go longer than 5-6 hours without nursing or pumping. Stop all pacifier use. Replace bottles with small cups. All sucking should be at the breast.
Pacifiers are often at the root of milk supply problems.
4. Consider why you are pumping. Pumping is a substitute for directly nursing your baby. Your feelings about being away from your baby may have a significant affect on how much milk you are able to pump. Spend as much time as possible with your baby. If nursing was not going well, your baby may have a poor suck.
