I have been exclusively breastfeeding since birth, she is only 12 days old but I already have horrendously cracked and sore nipples and mastitis in both breasts, everytime she latches on it feels like someone is pulling a knife down my nipple, im contemplating bottle feeding but I just cant bring myself to do it because breast milk is whats best for my baby it's just im in excruciating pain where im pulling my hair out to deflect some of the pain elsewhere. Please help, im crying my eyes out as im writing
