When I picked him up from school, he had had yet another accident (with #2 again). This time it only got on his pants, so I didn't have to wash another pair of shoes. I was totally clueless into why he had pooped twice during the school day.
Later that night, I talked with a friend about it. She asked if he had eaten anything out of the ordinary. I told her that Lucas and I went to Toot Sweets that morning for a muffin and some juice. She asked what kind of muffin. Turns out the muffin I had given him was basically a bran muffin. Oops!
