If you use a breast pump, set aside time each day or night for “power pumping.” The idea is that you pump, then rest, then pump again. The amount of time you actually pump should equal the amount of time you regularly spend in a breastfeeding or pumping session. For example: If you usually pump for 15 minutes you would pump for 5 minutes, then rest for 5 minutes, pump again for 5 minutes, rest again, and pump again for 5 minutes. This can train your body to produce more milk. You should see results after 2 or 3 days.
