When it comes to induced lactation, it would be more effective to use a breast pump as it is the nipple that needs to be stimulated in order to produce milk. The Noogleberry won't actually draw the milk out, so to speak, so I think that people who have lactated whilst using the NB are also using hormones, which would be the main culprit. I started using the NB only two months after finishing breastfeeding, and I never saw a drop of milk.
