Blood in baby’s poo

It can be a symptom of CMPA. Does baby have any other symptoms?

Could be soya or milk intolerance. If you're breastfeeding maybe stop eating foods that contain soya and milk and see how baby reacts in couple weeks. Then slowly introduce again milk and then if everything is good then soya.

Ours had this once at a similar age - the doctor thought he ruptured a vessel after doing a big poo earlier in the day. Since then there hasn't been a repeat. Worth keeping an eye, taking pictures for monitoring and getting them checked again if it persists

Was our sign that our daughter had CMPA

Blood in stool is a sign of inflammation which is usually an indicator of CMPA. My daughter has CMPA and she had blood

there are soooooo many things it could be, most benign but not all. CMPA is a possibility though it's also overdiagnosed and really rare to have this as an only symptom (according to our gp as we're currently trying to get our own LO investigated for the same issue). if it's bright red and just spots, get some nappy cream and make sure you really lather it on, including at the opening of the bum, as the most common cause is a tear and these are very common in babies whose digestive tracts are still developing. however if it gets worse, darker, or has mucus or doesn't clear up in a week then go to a gp. they may well direct you back to a&e just to rule out anything nefarious. as others have said, take photos and it might help to keep a log of when there's blood
