How to increase prolactin
Stimulate your breasts towards the end of your pregnancy.
Starting about 2 months before the baby is due, start to pump your breasts with an electric pump. This can stimulate prolactin production.
Start by pumping for 5 minutes, three times daily. Gradually increase this to pumping for 10 minutes every four hours, and then to 15-20 minutes every 2-3 hours.
