Tips for helping milk come in fast and strong?

First time mom here and hoping to exclusively breast my little one. I have extremely tiny breasts and it’s just always been a fear of mine that breast-feeding won’t work. I know that breast size doesn’t matter, but I can’t shake this fear. I’m 38 weeks now and actually want to start collecting colostrum, I did notice if I give my breasts, a good squeeze after a hot shower, a little drop will come out, which gives me hope! I also have gestational diabetes, so I wanted to have some colostrum on hand in case of a low blood sugar event upon birth.

But I’m also wondering from you experienced mamas, if you have found anything that really helps with milk supply coming in fast and strong? Of course I know that it is mostly about supply and demand and pumping will be really important. But if pumping doesn’t work? Have you tried any herbs, supplements , or other techniques that have helped? Grateful for your response responses.
