Re: Blood in diaper?!
Our son had blood in his stool at 6 weeks old. He was diagnosed with a dairy intolerance so I went off all dairy while I was nursing and filled up on other sources of protein (like egg) because I was constantly starving.
His reactions continued even after I went dairy-free because it turns out it was an egg allergy all along. I mention this because egg allergies can also cause bloody stool so it might be something to keep an eye on as you start introducing foods in the future.
