I had a really tough time with breastfeeding my daughter, who had a tongue tie. 2 years on I have been left with a 'hard' crusty layer on each nipple which is painful if I try to remove it & I assume is some sort of scar tissue. . Now pregnant again & terrified at the thought of attempting breastfeeding again or if I even can breastfeed with these horrible things!! Has anyone experienced this ??
