Clean all parts that come in contact with your breast and breast milk prior to first use. This breast pump is for household use only. As the pump is compact and discrete to use, you can take it with you anywhere, allowing you to express milk at your own convenience and maintain your milk supply. If your breasts are engorged (painful or swollen), you can express a small amount of milk before or between feeds to ease the pain and to help your baby latch on more easily. If you are separated from your baby and wish to continue to breastfeed when you are reunited, you should express your milk regularly to stimulate your milk supply. Note: This is not a rechargeable breast pump. This device can be operate on USB cable directly but cannot be recharge.
