Argh. Poor baby. Is this your only child? I know my second child got colds much more frequently than my first because my first brought them home and it was impossible to keep the house sterile. AND, my second child has allergies. He has the traditional allergies to dust, air pollutants, seasonal stuff from plants, cats, etc. He takes year round medicine now but he had a few early years where his nose ran constantly. Do you see a pediatrician monthly with her or every three? When is your next pedi visit?
