Baby boy made my nipples bleed :( since the hospital with my first feeding we didn't know I had flat nipples he took my breast normal and did some damage to them. Since then they've always been sore, that's why I use a shield to help him latch better . But today for some reason they started bleeding during feeding 😥 hurts like a bitch!
