Breastfeeding support

I’m currently 26 weeks pregnant with baby 2. I tried to breastfeed my son but found it impossible due to having flat nipples. I did however manage to express milk for him for 7 months which I am very proud of. I would love to be able to breastfeed this time around and wondered if anyone knows if there is any support I may be able to find anywhere. Midwives in hospital were great but I was in 3 days trying to feed him. I won’t want to do that this time as will have an 18 month old at home as well.
