once you become pregnant you can lactate any time. There was a mom who breastfed all her children, then she decided to adopt. She was not breastfeeding at the time, decided to pump and her milk came in time for her to nurse her adopted baby once she got her. So, you can lactate even if your not nursing. Also, when my sister just had her baby, and I was pregnant, I would start to leak when the baby cried, and my mom would feel let downs when the baby cried as well. certain emotions/hormones and stimulation can cause this stuff to happen.
