Long time lurker, first time poster, here. I'm feeling like a bad mom at the moment.
DS is eight weeks old. On Friday, while running errands, I stopped at Jamba Juice for a smoothie. I wanted a protein booster. I don't like to get soy protein because of the estrogenic properties, so I got whey protein.
Yesterday afternoon (Saturday - so like ~30 hrs later) DS had three poops with small spots of blood and a little mucus. Then it went away after that. He was very happy, slept well, didn't seem to be in pain or anything.
He is not a colicky baby. Never fusses excessively. Very calm. He's had a great appetite. Nothing about these items has changed in the last 48 hours.
I asked Dr. Google about it and find that blood in the stool is commonly indicative of cow's milk protein (i.e. whey) allergy. I had a large dose of whey on Friday.... Saturday, bloody stool.
It was only a little blood and it hasn't recurred, even though I had cereal with milk for breakfast on both Saturday and today. But still.... did I just do a horrible thing and cause a milk protein allergy where there was none?
