So this morning my son had a 101.3 fever. He was refusing to drink his bottle. I changed his diaper and noticed a light green diarrhea like poop with a weird looking texture. I just changed him again and it was the same. What could be wrong with him? I’ll post a picture of his diaper in the comments
