My LO usually has 4-5 dirty nappies a week, but has had 4 in the last two days (not diarrhea). They all seemed pretty normal except we found some stringy streaks of blood in them. Only a small amount, but enough to notice. He is otherwise completely fine. Anyone know what this is? Just something that happens or something to worry about? Edit: Other info - I was dairy free for the last fews (suspected dairy allergy in LO - reflux, tests said probably not the case -they aren't 100%) and returned to milk a few days ago. Don't know if that could be linked?
