Breastfeeding help!

Jessica

I am currently 28 weeks pregnant. I am hoping for some advice on how to make sure I can produce enough milk when baby is born. My last two I was only able to feed for about a month. Both times I got clogged and wasn't producing enough. I got so engourged but nothing came out when I nursed and barely anything when I tried to pump. I would really love to bf for 6 months atleast. I just need tips and advice on how to make this happen! Thanks
