Consider listening to relaxing music while pumping. More frequent pumping is generally more beneficial than longer pumping sessions when it comes to establishing your supply. Massage your breast for a few minutes before you begin pumping to aid with letdown and output. Letdown will also be encouraged by keeping your body warm during pregnancy. Pump in a hot shower or by a heat source such as a heating pad. Letdown can be discouraged by wearing a support garment while pumping. These garments are designed to allow milk to flow from the breasts without leaking through the clothing. Some common types of support garments include maternity bras, nursing bras, and pump pads. If you are planning on expressing some of the milk, it is important to keep leaked fluids away from your clothes since this could lead to wet stains that might be hard to get out of certain fabrics. Finally, don't feel like you have to express all of your milk. Breastfeeding mothers usually only produce enough milk for their babies. You should not feel guilty if you decide not to express all of your milk.
