My son has been having this weird diarrhea for about two weeks now , and it’s been giving him this horrible diaper rash , he’s literally pooping all day long , he’s not complaining about anything hurting but his diaper rash , he’s been up sense 5:30 this morning . And hasn’t gone back to bed and than farted about 3 times and I checked his diaper , and his diarrhea was this weird green color , like lime green . I’ll be calling his pediatrician today to make a appt tomorrow but has this happened to anyone? Or any nurses on here that may know what’s going on? Help a momma out .
