Hi all, looking for advice on baby's poo. Currently 8 weeks old and tonight has had Black in his poo, I have seen this in smaller amounts over the last week. Ds on lactulose twice a day and regularly needs a half glycerol supp to poo ( all consultant prescribed) Context- has had issues since birth with bowel/tummy but no solid answers yet, has had barium swallow/enema, biopsies to rule out hirschsprungs which did cause bleeding but was temporary and over almost two weeks ago now. He has also been on neocate milk for the last four weeks. Any ideas or advice what could be causing the black. No temperature present, generally fussy and colicky baby and no change to his usual temperament.
