My son, age 22 months, has been having episodes of green stool for the past month, on and off. Sometimes it's very loose, and other times less so, but it becomes very bright green and it stains his skin, almost like food coloring. He hasn't eaten anything unusual or green. In fact, his appetite is low and he's a very picky eater - mostly yogurt, fruit, crackers.
The pediatrician says it must be food-related, and she tested his stool for a bacteria that wasn't present.
Can anyone lend insight? I'm worried about him. Could this be a potential symptom of lead poisoning? He chews on everything - toys, books...I worry about him. Thanks.
