Diaper question.. I just changed my LO's diaper and I noticed he had "tooted" mucus. Not his normal stool or anything just plain yellowy mucus.. I have a picture but didn't post it don't wanna gross anyone out! Haha he's only 4months  and EBF. we haven't introduced solids yet. Has anyone else ever had this? Should I be concerned?
