Small boobs can breastfeed?

Noob question 🤣 but I was wondering , does people who have small breasts (A cup / B cup type) successfully breastfed their baby? I'm quite flat chested and I'm worried that it might contribute to a failure of breastfeeding as baby will have a harder time to latch on. I was unsuccessful with bf-ding for my firstborn , but I wanna try with my upcoming one. Bm is definitely the best for babies and I really don't wanna resort to formula feeding unless there's really no production. Care to share your experiences (for those with small boobies? But success in bf)
