What color are your LO stools? My daughter is 6 weeks old and is formula fed. Her stools were yellow and seedy looking, but lately they have been a greenish brown color. I didn't think anything of it until recently. She has had some vomiting, but we have tried a new bottle to help avoid gas and it seems to be helping so far (fingers crossed). Anyone else with greenish brown stools or should they still be yellow? Just wondering if this is something I should call the doctor about. TIA!
