Yes, you can bring in some milk by stimulating the breasts, but the amount varies from woman to woman, and you may never get a full supply. Most women must continue with supplemental feeding systems at least until their babies begin solids. Breasts make milk in response to stimulation, so putting your adopted baby to the breast frequently will bring in some milk. There are supplemental feeding systems that enable the baby to get formula at your breast. It is a bottle that is attached to a nylon cord that hangs around your neck like a necklace.
Tiny tubes are paper-taped to each breast.
The SNS comes with three different sizes of tubing. The baby nurses at the breast and gets the formula as well as stimulating the breasts. This book tells you everything you need to know. Consult with your lactation consultant or health care provider regarding the advisability of any opinions or recommendations with respect to your individual situation.
