First- is the blood in the poop or on it? On it is more of a fissure issue, but in it is something different. A had blood in her poop once while I was bfing (I freaked due to
DH's crohn's) but the ped asked if I'd had any breast soreness and said I was probably bleeding internally, but it was coming out through milk and she was ingesting it, hence passing it in her poop. If it continues for longer than a day or two I'd definitely call the ped, but see if you're sore at all or having boob issues. Good luck, Linda!
