Breast milk problems

Taneshia • I am pregnant with my third child and it was a complete surprise!!
So I had my first born 6 years ago and my milk never came in, I had all the signs of successful breast feeding except never got milk. 
This time I REALLY REALLY want to breast feed, should I do anything before the baby Is born that can insure my milk coming in? 
Pumping, eating certain foods, anything? I have no idea :(
