I breastfeed my son, and he was 8 months old when I started taking the apple cider vinegar for joint pain. At his age, nothing I ate or drank bothered his stomach, but when I was taking the apple cider vinegar he had frequent stomach aches, was very fussy, and would go days without bowel movements when he normally would have one twice a day. I would definately not suggest drinking apple cider vinegar if you're a breastfeeding mother.
