Oh boy I feel like a terrible mom. My nearly 18 month old drank from the dog's bowl about 4 days ago and has had dark sandy / gritty liquidy stools since then. They are liquid with these little hard dark sand like bits that are impossible to wipe off her bottom. This also happens to coincide with starting a toddler program last week, so I am not sure if she has a bug or if I should be taking her into the doctor. Any ideas? Thanks in advance!
