Many moms find a drop in supply when having to rely on their pump more frequently such as when they return to work.  They now have to us a pump to remove the milk several times a day and may struggle to keep up with the baby's demands.   Using the best quality pump with properly fitting breast shields is the first step.  When seperated from the baby, a double hospital grade pumping system is the most efficient and effective.  The double pumping personal use pumps are good choices when baby is nursing well and helping mom increase or maintain the supply when together.  If moms' note that they are not getting as much milk as previously, replacing the valves or membranes may be helpful as rips or tears can occur and decrease the suction and milk production.  Evaluating a pumping session may provide clues on decreased production as well as tips on improved pumping techniques.  By using a hands free pumping bra, mom can work while pumping to increase imilk volume.  Pumping once or twice a day when home with the baby can result in improved milk production when seperated as well as adding a night time pumping session if baby is sleeping more than 6 hours.
