Our pediatrician's office has a nurseline, so if we call after hours they can advise on whether a visit is urgent. The office is affiliated with the local children's hospital, and also has a kids urgent care center (and we have used both the ER and the urgent care). Most of the time the nurses are able to answer my questions and help me decide if immediate treatment is needed or if we can do a sick visit to the regular pediatrician's office. Does your child's pediatrician's office offer anything like that?
