Sick visits are usually scheduled on the same day for acute illnesses. Call the receptionist to schedule an appointment if you know that your child needs to be seen. You may also ask to speak with a nurse first to help determine whether your child's illness requires an office visit. You may schedule appointments in the future for chronic conditions such as asthma, obesity, ADHD, and wart treatments. Weekend visits can be arranged for urgently sick children. On weekends and holidays, the best time to call the doctor is between 8:00 am and 9:00 am to discuss the best way of obtaining care for your child.
