I sure did have one of these. She was sick the entire 18 months she was here. Always coughing and a runny nose, always on antibiotics. Brought in fifths disease, the flu and constant colds. Made everyone sick! Mom would drop her off to me saying she was up all night coughing and that mom was going to stay at grandmas and sleep all day but sent her kid to daycare anyways. Very frustrating. She has since left care and its been such a relief not to have to worry about what disease she would bring in next!
