Parents: Fun poop question......?

Is your daughter formula fed? My son is and he would have green poops from time to time and I asked the doctor and he said it was from the iron in the formula and the reason why it was not consistently green was because it depended on how quickly his body processed the formula. Now that he is on solid foods it's pretty much normal "brown" poop..lol. If he gets green or yellowish poop now thats a sign to me he could be sick. Last time this happened he had ear and sinus infection. I at first thought it was teething but then he lost his appetite and I got worried. I would say unless anything else changes with her then no worries.
