Breastfeeding 😬😬

I'm 36 weeks and pregnant with baby #3 ( 11 year old, angel baby and now pregnant). My question is, is there anyone else nervous about breastfeeding? This will be my first time because my oldest had a hard time so she was switched to formula. I went to a breastfeeding class and I have a lactation nurse, I'm just scared that my baby girl won't latch on, or I won't know how to pump, or I won't produce enough milk for her. I'm totally okay with delivery because I know what to expect, but I'm very nervous about breastfeeding. I just want the best for our Munchkin.
